Hello,
I want to point out I face the same issue on the latest Linux version (2021.31) running Manjaro "Pahvo" 21.1.3, kernel 5.14.2 on proprietary nvidia driver version 470.63.01 (GPU: GTX 1070). The terminal output the following message at the time of the crash: "The futex facility returned an unexpected error code."
Got the bake I wanted on the latest 3DCoat (2021.53) version for Windows OS with no issue, same computer.
Which mean that's probably something that the developer team should pay attention to for the futur release(s), probably just a simple update issue (running higher version of a tool/library than the one integrated by the software).
