I am currently updating via the terminal from version 18 to version 20, hopping across versions. Whist upgrading from version 19.0.7 to 20.0.5 I keep getting stuck at the following error :

When I checked the size of the “oc_filecache” in the database the file is over 46GB in size which seems excessive.
I have tried to run “occ files:scan --all” however I get the following error:
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
There are no commands defined in the "files" namespace.
Any help would be much appreciated.
