basically there was a moment when I changed a user variable in my home config without thinking, immediately regretted it and changed it back, but it didn’t help. I tried asking every AI chatbot and searched all the existing issues, but still can’t figure out how to fix it. I also tried rolling back to the previous generations, and rebuilding with a specified user variable but it didn’t help either. my user is niko, w4le5 is a non-existent user that I applied by mistake.

I cannot nor want to reinstall, please someone help me

Here's console output after a build attempt, printenv output, and configuration files:
