System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.93
Processor: ryzen 5800x
Blender Version
Broken: version: 3.2.1, branch: master, commit date: 2022-07-05 15:44, hash: a2d59b2dac
Worked: (worked on the 3.1 version then the bug happend two days ago, update to the latest version didn't help, also tried the attached file in the latest 2.93 LTS and it crashes the same way)

Short description of error
Crashes when changing or removing a material in material properties in a scene with very complex materials. I've been working on the scene for several months (blend file size reached 9 gigs without textures), everything worked great until the bug started. Simplified scene to the plane and 6 most complex materials that can't be removed at this point because blender crashes. Doesn't happen in a clean scene, but happens when appending the materials to another scene

Exact steps for others to reproduce the error
Open material properties and: scroll up and down;
change one of the materials: remove one of the materials

Tried again with the blender_debug_gpu_glitchworkaround.cmd. Same crash, attached new log.

Thanks for the report. Removal of material didn't result into crash. Does this happen after performing sequence of steps?
Please upload crash.txt file: E:\Digital art\Blender\temp\material scrolling crash.crash.txt

It happens even when simply opening the material properties tab and then scrolling up and down a couple of times.

Hi again! I've reinstalled the windows and the problem still persists. I've tried to reproduce the crash on another machine (laptop with gtx 1050) and it worked fine, no crashes. So it seems something in my configuration is off. Here's the .txt file you asked for after i reinstalled windows. I hope you could help me find the culprit.

After more testing I've found that my project files have been on another SSD in my systsem and it might be causing the problem. I've copied them to my main SSD (now blender.exe and the project files are on the same drive) and most of them started working properly apart from one huge file - still same behavior and crash. Any ideas what else can be tested? And how can I analyze crash log to understand what is causing the problem?

@Ivan-75 hi, could you upload screen recording to give an idea of exact crash reproduction steps (they are still unclear to me)?

@PratikPB2123 , Hi! As you can see the file crashes when it's on the disk E. When I copy it to another directory on the same drive or on another drive - works fine. But. there is a bigger file with the same textures that crashes in the same way no matter where it's stored. Can it be that the file became corrupted in some way because the problem started not so long ago hardware-wise I've checked the gpu and run memtest - no errors.

Hi, I think I've figured the root of the problem - my ssd with all the project files got corrupted somehow, but it seems that blender is unable to access them so it keeps crashing. No idea why that happened but here I am. Thank you for your feedback and time!
