Blender 2.93 Crashes on Startup

Support Technical Support

Hello , When i Start blender, it instantly crashes, i did a factory reset on my computer and before i did that, everything was working fine! Sometimes i can use it but it instantly crashes with no warning!
AMD GPU Drivers are all up-to-date, but my GPU has been doing some “beeps” and miliseconds freezes once in a while, while playing games but never crashed anything! Only getting these issues in Blender , i only use it for Making Mods for the Racing game “Assetto Corsa”.
i can leave a link for the scene i’m trying to open, but no other scene works here, Blender crashes either Empty or opening a Scene so… Please help! :frowning: :disappointed_relieved:

Not a developer but I had this issue yesturday, tried uninstalling and reinstalling nothing worked. only going into app data and deleting the folders fixed it for me, must of been a plugin that was stopping it C:\Users*******\AppData\Roaming\Blender Foundation\Blender

Sounds like an AMD driver issue

Same problem with me Blender under Windows10 version 2.93.2. I found this and that works with a startup:
C:\Program Files\Blender Foundation\Blender 2.93\blender_debug_gpu_glitchworkaround.cmd

I gues that this looks at the older videocard - settings.

Try this in a command window: blender --debug-gpu-force-workarounds and it started with mine :slight_smile:

or change your shortcut as “C:\Program Files\Blender Foundation\Blender 2.93\blender” --debug-gpu-force-workarounds

Today I’m using the latest Blender 3.5.0 and it still works fine on my very old graphics card AMD Radeon HD 6570 with the same shortcut:
“C:\Program Files\Blender Foundation\Blender 3.5\blender_debug_gpu_glitchworkaround.cmd”

Unfortunately, the original installed shortcut to “C:\Program Files\Blender Foundation\Blender 3.5\blender-launcher.exe” still doesn’t work on this graphics card and not start.

Hi, i also have the same issue and had to use that shortcut. It usually works on the material view but once I switch to render view blender will just crash. So, do you have any workaround? You maybe have no solution but what’s your workaround?
