Everything is yellow and the letters are white

Hello everyone,
this is my first post in this forum and I'm from Germany, that's why my english isn't the best.

My problem is, that I recently downloaded Kali Linux and everything was fine. But after I executed the command "sudo apt dist-upgrade" everything was yellow an all texts and letters and stuff like that was white (pretty shitty contrast).
A few days later, I deleted the OS from my PC completely. But a few hours ago I gave Kali one more shot. After I installed it and booted it for the first time, it was as yellow as it was before.

Can anyone please tell my where the Problem is. I also installed the NVIDIA driver for Linux and executed the .run file, but it is still yellow and white.

Greetings
Erik
