I'm terribly sorry, but it seems I've encountered another issue. When the renderer backend is set to Metal (with Vulkan enabled or disabled, the result is the same) and GPU acceleration is enabled (it runs normally if turned off), calling OpenGL ES causes UTM to crash.

I also tested UTM 4.7.5, and enabling GPU acceleration with the OpenGL renderer backend still causes UTM to crash when invoking OpenGL ES.

I tried to reproduce this issue on Debian 11, but the debug.log file seems to show that everything is normal while UTM crashed...

@tangxinyi9420-oss Can you run https://github.com/utmapp/UTM/actions/runs/21341695148/artifacts/5251276653 and provide debug.log? It does not fix the issue but it will print more details in the log so I can try to track down the issue since I cannot reproduce it here

Also can you test 4.7.4 with Metal as well?

I have completed testing the version you provided. The log file has been uploaded.

It seems that this program requires OpenGL ES 3.0 or above. Since version 4.7.4 does not have Vulkan, the issue that causes UTM to crash does not occur. The program will simply report an error stating that the OpenGL ES version is too low.

Good, thank you! I downloaded and tested the latest build version following the link you shared, but strangely it has reverted to the previously mentioned black screen state. The results are the same whether the renderer backend is set to Metal or OpenGL.

I see the check I added was too strict and made gnome-shell fail as well.

I am very sorry, but the crash issue still persists, and the debug logs continue to show the same error as in #7593 😫

I think I know what the issue is but to make things easier, can you provide instructions to produce this crash or upload a copy of your utm if it's not confidential. Otherwise, let me know what ISO to install in a new VM and what app to run to trigger.

Certainly, it would be great if this helps. I have uploaded a copy of the system to Google Drive.
