Unity keeps crashing when switching between dx9 and dx11

Hello,
This is a problem that i've had for a long time, even made a thread about that and sent a bug report but nothing changed.
I suspect it's something inside the project folder but i never found what it was.

here's the log when it tries to switch between dx versions:

Even deleting folder by folder until i don't have anything in the project can fix it, and if i have dx11 shaders, the scene window can't even render the scene...

Does anyone have any idea on how to fix this?

 

Really need some help with this, maybe someone from Unity could see this and help me figure this out...

Here are the known issues that are probably all connected:
- Unity always crashes when switching between dx9 and dx11,
- Having dx11 shaders in the project folder will make it impossible to render anything in the scene view and game view even if those shaders aren't being used,
- RTP V3 doesn't compile new shaders,

Here are some things i've tried but all failed:
- export everything to a completely new project,
- delete folder by folder until i have nothing left,
- delete all shaders,
- delete the library folder and everything on the root of the project folder (except the folders).


This is probably something related to shaders. I do have some strumpy shaders, but i already tried to delete them and it's still the same.
A long time ago i downloaded the unity built-in shaders from the official place for some unknown reason, don't know if that could be the problem but i downloaded the latest built-in shaders and nothing changed.

Any ideas i could try?

EDIT:
Here's a new update, i've been deleting folder by folder and switching between dx9 and dx11 every time i did it (crashing every time). This last time something different appeared:

Any ideas?



EDIT 2



Well couldn't find the problem again, so i started to delete folder by folder from the beginning again. This time it didn't crash at first but crashed when i switched for the 3rd time...

37. Crash!!!

 

Seriously, i can't even understand how this is still happening...
I literally deleted everything from the project and it still keeps crashing...
It can't be because of the graphics card, because the same thing was also happening when i was using my laptop months ago...

 

Happens to me too when i transition from 11 to 9. Try having the editor camera not looking at the level geometry. You may avoid the crash some times..
