There seems to be problems with the fileaccess control app. If you have access via terminal you can either try to update the app or at least disable it. See if it is working then.
No -> check for new information and ask here again
Yes -> If you reinstall it through the app store, it gets the latest version. Still a problem-> probably a bug -> https://github.com/nextcloud/files_accesscontrol/issues

what @tflidd says…

plus: i’d try the manual updating process on commandline to get update done. manual tells you how exactly.

thanks for your feedback

https://docs.nextcloud.com/server/latest/admin_manual/maintenance/package_upgrade.html#upgrade-tips

the Problem i have to use the command, i don’t have sudo so i am confused how to use it, without sudo the command not work ;-(

I’m not sure if the app is part of the core. If not you can just try and delete the app folder:
/var/www/html/nextcloud/apps/files_accesscontrol
