Had the same error. Finally, for me the reason was "oc_filecache is corrupted". Try to check the database tables for errors. If also the table oc_filecache is corrupted try the following: 1. stop nextcloud container 2. clean database table - truncate nextcloud.oc_filecache - check table nextcloud.oc_filecache (nextcloud is the database name and oc_ is the table name prefix, both of which are specified during setup and can differ on your system.) This will delete the entire contents of the table, which is fine for oc_filecache, since it will be rebuilt by the server. 3. restart nextcloud container
