Blender 3.0 fails to load, hangs on reading from the user prefs #91286

System Information
Operating system: Windows-10-10.0.19041 64 Bits
Graphics card: GeForce GTX 960M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 391.25

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-09-04 16:28, hash: 079bd11556
Worked: (newest version of Blender that worked as expected)

Short description of error
Different daily builds of Blender 3.0 fail to load most times without any errors recorded when launched from cmd and sometimes load only after system restart. Other versions of Blender load without issues.

Exact steps for others to reproduce the error
Open downloaded folder for Blender 3.0 Alpha and launch the blender.exe file, it would run but Blender won't load. Running blender_debug_gpu_glitchworkaround.cmd nor blender_factory_startup.cmd made any difference.

Thanks for the report. Was this working for previous blender versions?

Can you please try again after upgrading the driver?: https://docs.blender.org/manual/en/latest/troubleshooting/gpu/windows/nvidia.html

Yes it works for previous Blender vesions. I use 2.8, 2.92 and 2.93 without issues.
I will have a look at the driver upgrade.

The driver is up to date.

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.

Changed status from 'Archived' to: 'Resolved'

Issue persists, exactly as reported, even with latest stable version of Blender 3.0.
Log files are empty because Blender does not crash, it just does not load, displaying ''not responding'' indefinitely until forced to close.
