AIO stuck on starting Nextcloud-AIO-Nextcloud container

I’m stuck getting Nextcloud AIO up an running. The Nextcloud container seems to be stuck, as Apache and Notify Push are waiting for it to start:

The Nextcloud container logs the following:

Connection to nextcloud-aio-database ( 5432 port [tcp/postgresql] succeeded!
+ '[' -f /dev-dri-group-was-added ']'
++ find /dev -maxdepth 1 -mindepth 1 -name dri
+ '[' -n '' ']'
+ set +x

I am running unRAID 6.12.6 and am in the progress of making a new instance of Nextcloud AIO, after having used Nextcloud without AIO for a couple of years now.

Edit: Now the logs also show this:

Configuring Redis as session handler...
The initial Nextcloud installation failed.
Please reset AIO properly and try again. For further clues what went wrong, check the logs above.

I have followed the reset instructions once already, only to end up at the same issue. The only thing I think I could change at the moment is to change the unRAID Docker storage from an image file to a directory.
