Link to debug log

The debug log isn't accessible since the app doesn't start. Chromium latest works fine. Electron fiddle does not work. AMD RX6700 with open source Mesa drivers and AMD ROCm 6.2 that works fine for it's intended compute workloads and GUI acceleration. --no-gpu doesn't work. --disable-gpu doesn't work. --disable-gpu-sandbox doesn't work. --in-process-gpu --use-gl=desktop doesn't work.

This looks like a duplicate of #6855

The workaround in that issue is this: #6855 (comment)

sudo apt remove mesa-va-drivers

[scottnonnenberg-signal]

Please let us know if that works for you!

Please let us know if that works for you!

I'll do that tomorrow as a test run to see if that is the issue, but I will not be able to leave those drivers uninstalled because I use the va drivers heavily for compute and encoding projects.
