Help Needed - 2013 Audi A4 Avant S-Line MMI 3G+ Stuck on Splash Screen

[JediWill89]

Hi everyone,
I'm having a serious issue with my 2013 Audi A4 Avant S-Line MMI 3G+. Recently, I went into the green engineering menu to make some adjustments, and now my MMI is stuck on the splash screen.
Here are the details of my problem:

The MMI is stuck on the splash screen.
All the buttons work.
The radio works.
Bluetooth works.
I can't see my rearview camera feed.

I believe I might have messed up some settings in the green menu, but I'm not sure which ones or how to revert them back to the original state.
I would greatly appreciate any advice or guidance on how to fix this. Any step-by-step instructions or references to similar issues would be incredibly helpful.
Thank you in advance for your help!

I'd suggest a cold reboot of the MMI by pulling the corresponding fuse. Also let folks know what changes you were attempting to make; that might provide clues to potential causes.
