Many error messages since update to NC 11 beta 2

Hello, I updating from nextcloud to NC 11 BETA 2. now I have these error message whenever I connect to my cloud.
Is this an error of the music app? The app works fine…

Object of class OCA\Music\App\Music could not be converted to string at /var/www/vhosts/
trim() expects parameter 1 to be string, object given at /var/www/vhosts/
Illegal offset type in isset or empty at /var/www/vhosts/
Illegal offset type at /var/www/vhosts/

For beta versions it is better to post issues directly to the bugtracker. It’s a busy time for developers and they are not always checking the forum (filtering for beta-testing messages is a bit hard).

By disabling the music app you can easily find out if this app is creating the issue.

Okay thanks, I will do it.
