Empty Log-Page after update

Apache/2.4.53 (Debian)
After having done the update to 24.0.1.1, the log-items are not listed when choosing Settings/Logging. Log-items show up for a very short moment and disappear again.
Adjusting file ownership and permissions does not resolve.

Maybe related entries in Nextcloud.log

If somebody knows how to resolve, some guidance would be great.

Actually it takes about 30s for the listed log items to disappear again. Don’t know what happened.
Most recent item:

[scss_cacher] Fehlersuche: SCSSCacher::process ordinary check follows

GET /settings/admin/logging
from <WAN-IP> by <user> at 2022-06-01T00:27:30+02:00

Before above is happening, following event is logged

[logreader] Fehlersuche: Could not find resource file "/apps/logreader/css/../js/logreader-main.css"

GET /settings/admin/logging
