BLACK SCREEN problem

[luv train]

My Wallpaper Engine doesn't show some of the wallpapers
The selected wallpaper's sound still works, but the image/animation doesn't - it's just a black screen
What have I tried?:
Reainstalling the app
Updating/Reinstalling my graphics drivers
Deleting/Changing to default my 3D graphics options in Nvidia Control Panel
Tried the CodecTweakTool
Ran the diagnostics option when starting the app
Checked the permissions in the Firewall
My antivirus doesn't block the app

Are there any other options to solve this?
I've used this app before, and it worked fine

My hardware:
GPU - RTX 2060
CPU - AMD Ryzen 5 3600

It sounds like your system does not support the video codec of the specific wallpapers for some reason (so most of the steps you tried are irrelevant and will not help ).

It sounds like you read the relevant page already:

However, you did no mention the last step on that page, which is to switch to LAV with DirectShow. Please try this, it helps the vast majority of users who have severe video codec issues:

I've remembered that I had a GPU from a different manufacturer and maybe some of the leftover drivers were the problem. So I clean deinstalled the old drivers and reinstalled the ones that were relevant to my current GPU with the DDU and that seemed to be the issue. But thanks for the response
