Cant enable / disable apps in version 28.0.4 deployed on kubernetes with helm

i deployed nextcloud with helm chart
my nextcloud version is “28.0.4-fpm-persianfont-v1”
when i want to add ldap app to nextcloud it says:
Error: This app cannot be enabled because it makes the server unstable

i deployed a instance 4 month later with the same version and enable/disable app was working.
but now that does not work either.
why its not working now

Please check your Nextcloud log for details.
