The log shows "Renderer: GDI Generic". This message means that the proprietary graphics driver is absent from the system. Please install the proprietary driver:
NVIDIA https://www.nvidia.com/Download/index.aspx
AMD https://www.amd.com/en/support
If your system is a laptop, plug it into the power adapter. The laptop on battery may use an integrated Intel adapter (older versions of Intel adapters don't support OpenGL properly). But when the laptop is plugged into the power adapter, it uses a dedicated graphics chip (check for dedicated graphics in [RMB] START > Device Manager > Display adaptors). Note that "NVIDIA Control Panel" in "Manage 3D settings" allows you to select between "High-performance NVIDIA processor" or "Integrated graphics".

In the actual build of "3DCoat" you find new option "VSync" inside menu "Edit > Preferences" (please see the attached screenshots).
Works under DirectX and OpenGL.

Please download "3DCoat 2023.25" for macOS:
https://pilgway.com/~sergyi/links-macOS.html
For an unknown reason, the tab "Render" was crashing in "2023.23", built using the "Release" configuration (even on my Intel Mac). But it works in "2023.25".

According to the log your system doesn't support any graphics acceleration (field "Renderer" states "GDI Generic"). According to Google your laptop Yoga 720 uses NVIDIA graphics (https://www3.lenovo.com/us/en/laptops/yoga/700-series/Yoga-720-15/p/88YG7000828). Thus you should install proprietary NVIDIA graphics drivers from NVIDIA web-site (http://www.nvidia.com/Download/index.aspx?lang=en-us). Also try to run DirectX version of "3DCoat" instead of OpenGL (executable file 3D-CoatDX64C.exe" which uses DirectX).

Hello, Armored_22 and all XP-PEN users. To use XP-PEN with "3DCoat" please enable "Tablet PC" mode: 3DCoat > Edit > Preferences > Brushing > Tablet Interface > TabletPC (instead of WinTab).

The second screenshot reveals that the system doesn't have proprietary graphics drivers. Note the string "Renderer: GDI Generic" (means "no hardware OpenGL"). Install proprietary graphics drivers for your graphics hardware:
https://www.nvidia.com/download/index.aspx OR https://www.amd.com/en/support

"3DCoat" is trying to create a user data folder (which contains user settings and assets) inside "C:\Users\USER_NAME\OneDrive\???????\3DCoat". That is incorrect. It should create it inside "C:\Users\USER_NAME\Documents\3DCoat". To workaround this problem:
Start > start typing "Edit the system environment variables" > Environment Variables... > System variables > New... >
Variable name: COAT_USER_PATH
Variable value: C:\Users\USER_NAME\Documents\My3DCoatData (specify your user name inside)

Just now I have rebuilt and re-uploaded 2022.57 for macOS: https://pilgway.com/~sergyi/links-macOS.html
macOS HiDPI scale has been limited to "2.0"

Our global license server is "188.138.102.74" (aka "pilgway.com"). The port is 80.

After numerous requests from Linux users, "3DCoat" adopted "spacenavd" a while ago.

This problem has been fixed since "3DCoat 2022.11". The links to the latest "3DCoat 2022" for macOS are always here:
https://pilgway.com/~sergyi/links-macOS.html

On start-up "3DCoat for Linux" automatically enables tablets which it is able to recognize. Otherwise the tablet should be enabled manually by defining the environment variable "COAT_PEN" equals the name of the input stylus device. For example:
export COAT_PEN="Wacom Intuos3 4x6 Pen stylus"
Since "3DCoat 4.9.70 for Linux" it outputs into the Terminal the list of your input devices. Please see the attached screenshot as an example. You have to send a screenshot with the name of your input stylus device (similar screenshot as the attached) to me (support PERIOD linux AT 3dcoat PERIOD com). Then your input device name will be added into "3DCoat" to automatically enable it in the future builds.

Since "2021.83" the crash in AUTOPO under macOS is fixed.
The links to the latest "3DCoat" for macOS are always here:

"3DCoat 2021" for macOS had a problem with the Wacom tablet. Please try the latest "3DCoat 2021.59" for macOS:
https://pilgway.com/~sergyi/links-macOS.html
The Wacom tablet should work correctly: no missed strokes and no pressure problems.

Good day! First of all please note that "3DCoat 2021" and "3DCoatTextura 2021" clients have "FServer" built-in. You have to click "Load license" and open your file "FLOATING.license" directly inside them. Generally, there is no need to install and configure "FServer" for "3DCoat 2021" and "3DCoatTextura 2021" when your client machines are able to connect to the Internet. Only when your client machines with "3DCoat 2021" and "3DCoatTextura 2021" are not able to connect to the Internet but your server machine with "FServer" can connect to the "Internet" then there is a need for a local license server "FServer". Please see more in the document https://pilgway.com/~sergyi/FServer/FServer.pdf
That said here are answers to your questions:
1. Yes, the local license server "FServer" which supports "3DCoat 2021" is available for macOS.
2. No, because you don't even have to install the local license server "FServer" for your scenario. Click "Load license" inside your all "3DCoat 2021" clients to load your "FLOATING.license". "3DCoat 2021" clients will acquire your floating license from our global license server pilgway.com (188.138.102.74) through port 80.
3. Yes, because the local license server "FServer" is intended to replace the Internet connection from "3DCoat" clients to our global license server "pilgway.com" with the local connection between "3DCoat" clients and local license server "FServer".
4. Yes, a floating license is recommended for several users. But in "3DCoat 2021" it can be used without "FServer" in case "3DCoat 2021" clients can connect to the Internet.

This is because OpenGL on your system is using "Mesa" graphics driver provided by "VMware, Inc.". Is this virtual machine? 3D-Coat only supports proprietary graphics drivers. For example here is described how to install NVIDIA proprietary driver: http://pilgway.com/~sergyi/LinuxDocs/LinuxGraphicsDriver.pdf
