Internal Server Error, I have no idea what is wrong

Nextcloud version (eg, 20.0.5): 20.0.6
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04.2 LTS
Apache or nginx version (eg, Apache 2.4.25): Nginx 1.19.6
PHP version (eg, 7.4): 7.4.13

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Yes
I made an Upgrade an I’m facing the error “Internal Server Error”
