Empty files page after upgrade to 23

Nextcloud version (eg, 20.0.5): 23.0.3
Operating system and version (eg, Ubuntu 20.04): Debian buster
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.38
PHP version (eg, 7.4): 7.4.26

After upgrading my nextcloud installation from 21 to 23, the files page remains empty.
I dont see any errors in nextcloud- or webserver log but loads of errors in the browsers debugging console.

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