The issue you are facing:
after upgrading Nextcloud, PHP and installing php-fpm the Files tab in the Webui crashes.

All the other tabs work just fine.
File sharing also does not follow links - but I am not sure if that is because the Files tab is crashing.

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

It is happening every time since the upgrade.

Turns out that the read only apps directory had become unreadable.
even though the files and directories were also in the writeable apps directory it just crashed rather than emit an error.

I had to chmod 755 /usr/share/webapps/nextcloud/apps

Then it worked.
