Checking on google i found a thread on this board https://help.nextcloud.com/t/app-php-is-deprecated/93222, so i made the change on the config.php
After that i got:

No changes on settings or permissions were made. i managed to log in one time, was on the dashboard and the calendars. when switching to the files, it crashed.

anyone got an idea? thanks a lot.

How did you upgrade? Manually, then check the permissions. Seems to be the dashboard app, if not try to disable and enable (via occ CLI)
