Unable to start-up Coh2 on new computer

Hello, after a long time trying to fix this issue without success i come here in hopes someone has met this and been able to solve it.

I have been unable to start Company of Heroes 2 on my newly built Windows 10 high-end computer. Everytime i start up the game it crashes as soon as it reaches the black screen (When the vídeo would start playing). Looking at the warnings file in Documents the issue looks to be graphics/shaders related. The last part of the file goes like this:

18:05:48.02 SPDx11 -- [1] GPUs found.
18:05:48.02 ShaderDatabase: using shader profile [ps50]
18:05:48.06 Unable to load shader [coh2_impostor_billboard] so replacing with [defaultshader]
Application closed with error code 1129468744

By my own knowledge and looking online, so far i’ve tried the following:
- Started as administrator
- Used compatibility mode
- Tried the “-nomovies” and “-refresh x” options on Steam
- Cleared AppData Coh2 related folders
- Reinstalled the game
- Changed the start-up .ini file to use Directx11 instead of 9
- Changed settings on GeforceExperience to lowest allowed
- Disabled NVIDIA streaming service
- Disabled Windows real-time protection
- Cleaned Registry and used /scannow to check for any faulty Windows System files.
- Copied files from a working game on a different computer and replaced them on the new one
- Tried deleting “Scenarios” folder on the game files as well as check for any MPScenarios.1.sga files (which were faulty in previous years)

Honestly, im almost giving up. The only thing i havent tried yet is to install the game in a diferente Storage disk or reformat Windows 10 entirely (a solution i cannot easily do because i have a bunch of work related stuff installed).

Thanks for your time and hopefully you can provide some additional help.

download Display Driver Uninstaller
Remove GPU Drivers
Restart
Then reinstall your GPU drivers
Restart
And try open the game again

Hello, thanks for the taking the time to look at the post. Sadly the issue persists.

This looks like the same issue, the first post from PureBunk explains a fix: https://steamcommunity.com/app/231430/discussions/3/540744936247412395/#c540744936248879024
