please help - Blender 2.80/2.81/2.83.5 etc instant crash on Open/Save/Import/Export?open or close Prefs window #80247

System Information
Operating system: Windows 10
Graphics card: GTX 1070
i7 980x

Blender Version
Broken: Any version after 2.8. 2.79 working fine
Worked: (newest version of Blender that worked as expected)

Tried installing and using portable version.

Short description of error
Open Blender then try to open (any file) or save a Blend file (even save default scene), or import or export a file, or open and close Prefs window and Blender crashes.

Can use Blender as normal for modelling, cloth sims, sculpting etc but as soon as I try any of the above (open/save/import/export/prefs window) Blender crashes.

Sometimes i can export or save a scene if I Open the prefs window and leave it open (in the background) while saving/exporting. This doesn't always work though.

Have tried numerous versions (from 2.80 through 2.83.5), numerous GPU drivers (including latest), tried deleting prefs folder and doing clean install. Tried changing Windows theme to default.

Exact steps for others to reproduce the error
As above. Based on the default startup file.

Please help me fix this.

Thank you for your report. Please download Blender 2.90 from here , open Blender's installation directory and double click on the blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Try to make Blender crash again. Once it crashes the Windows Explorer should open and show you two files. Add them to your bug report by clicking on the upload button as shown in the screenshot below. Please also upload the crash log located in C:\Users\[your username]\AppData\Local\Temp\blender.crash.txt.

Blender 2.90 is needed because it creates a stack trace in the blender.crash.txt that hopefully allows us to identify the issue.

thanks for your help. i followed the procedure above and when Blender started i opened the Prefs folder, closed it and Blender crashed.

Are you using a graphics tablet? If yes, please try to update the driver for it.

yes i am using a tablet (Huion H58L).

can i disconnect and try without or do i have to install a different driver? newer drivers seem to cause more problems than they solve...

just tried unplugging the tablet and started Blender but still crashing as before.

The crash appears to be caused by the wintab32.dll which is part of the graphics tablet driver. The issue likely won't be fixed without a driver update. It seems your specific tablet model has reach its end-of-life though, since the most recent driver is from 2017 on Windows.

thank you.

i installed the latest tablet driver and so far no more crashes :)
