Short description of error
After some time, when I try to open blender, it instantly close (0.1sec of console appear before closing)

The only way to make it work again, is to restart my computer.

The already opened blend files still work, just i can't open a new one.

If i close all opened blender, i will work.

To run many instances of blender at the same time again, I have to restart the computer.

I have tried to open it with PowerShell to see what it tells, but nothing..

Could you try running blender with blender_debug_log.cmd (or from the command-line with blender.exe --debug-all) and give us the logs?

I will update this task when the bug occurs again.
Since I restarted my computer, it now works fine...

I will close this task for now.

It seem's that the bug was from my computer, discord and firefox sometime crash for the same reason.
Maby two gpu, with an HDMI on one gpu only, and 3 display port to the other gpu for 4k screen, but with duplication of a screen with downres to 1080p for the HDMI can sometime cause crash in blender, and in some other programs.
