What could be the reason for this error? I have tried to find any solution for this but not really sure what to search for… If more info is needed just ask, I don’t really know what is needed or not.
Any help would be appreciate

After uninstalling then installing onlyoffice and the documentserver_community, i get this error:
Error: Trying to access array offset on value of type bool at /var/www/html/nextcloud/lib/private/Files/Storage/Wrapper/Encryption.php#439
