Hello @al98murru, sorry, but Proton generally expects that you have a Vulkan capable GPU, and the video driver for Intel Sandy Bridge generation doesn't provide that. Most games will fail due to a lack of hardware features and it's likely your hardware is unsupportable.
Setting that aside, you're using mesa/crocus from newer mesa, not mesa (amber) / i965 userspace driver. There's a chance this is a video driver sided issue.
Hi @kisak-valve. I globally disabled vulkan from all versions of proton installed on the PC from the "user_preferences.py" file, ergo the absence of vulkan is not the problem. It worked wonders until the 23.1 version of "mesa" came out which gave this problem on every game (steam or not). By switching to Mesa-Amber, I managed to curb the problem for wine games but strangely not for proton ones (except versions 3.16 and below).
if the problem came with a driver update and was affecting things outside proton I think you should report it to mesa here: https://gitlab.freedesktop.org/mesa/mesa/-/issues
Nothing extracted yet.

Symptoms
No game starts (at most the launcher in morrowind is displayed), when I try to use a version of proton higher than 3.16.
Checking all the logs I get this error:
