NVIDIA GeForce Experience Error Code 0x0003 – can't open it at all

[mardkhar]

Hey, been stuck on this for a day now. Every time I launch GeForce Experience I get error code 0x0003 with the "Something went wrong. Try rebooting your PC" message. Rebooted multiple times, nothing changed.
My specs:

RTX 3070
Windows 11
144Hz monitor

Anyone dealt with this before? What actually fixed it for you?

Welcome to you! But wrong section!??

But use DDU (Display Driver Uninstaller) tool on SAFE mode.

As mentioned, try a complete cleanup with DDU. But other than that, why not use the Nvidia App instead of GFE? Isn't it supposed to be a replacement for it?
