Still crashes after "load factory settings". This is the output from blender_debug_log.cmd after a crash.

Additional information that I forgot : it started to happen after I loaded 2 custom matcaps from my harddisk. It was the first time I tried to load other matcaps than the defaults.

Strange, the output txt should present some message about the crash. Like EXCEPTION_ACCESS_VIOLATION or something.
Can you try to run blender_factory_startup.cmd and blender_debug_gpu.cmd? (also in blender directory)
After Blender closes, the logs should be in a text file which can be attached here.

The crash occurs in vcruntime140.dll. This is not a blender library. The problem must occur when trying to read the image files for the matcap.
Try to install the official blender without being through the zip.
Perhaps this is a result of a bad installation.

The bug is still in 2.83.3 and 2.90 beta from july 24th.

BUT it is fixed in 2.91 Alpha (build from July 24th). not longer crashes on matcap selection screen.

Good to know.
Since it is a specific error in this setup, I don't think it is considered a critical bug to be backported to Blender 2.83.
Thanks for the report.
Closing.

Hi, I spoke too fast. The bug is still there. Crash after clicking on the matcap library button, so I can't change matcaps. These are the logs for version 2.90.1
Could you please reopen this report? thank you!

Can you check if blender runs out of memory, using the task manager or equivalent?
Also retry after moving C:\Users\guill\AppData\Roaming\Blender Foundation\Blender somewhere else so that Blender can start afresh.
Also, retry after gpu driver update.

I agree with @ankitm. You should try to rename/move the C:\Users\guill\AppData\Roaming\Blender Foundation\Blender\2.90 folder and check if this resolves the issue. This ensures that no old files from the previous attempts are left around.

No activity for more than a week. As per the tracker policy we assume the issue is gone and can be closed.

Thanks again for the report. If the problem persists please open a new report with the required information.
