Could you please provide the webserver (apache2 or nginx) error log.
The logfile you provided is the nextcloud log.
Those errors are not responible for the internal server error.

Where can the webserver log be found?

/var/log/apache2/error.log

You defined it in the installation in your Webserver config file

And now i don’t have an server internal error but some nextcloud error:

this would seem to be a config.php file problem and from the first pic I would ‘guess’ something to do with the way you have your POST setup for nextcloud admin notifications.
remark out the entries for this and see how that goes
again a simple reinstall would probably fix it.
