For what it's worth, as a workaround, I was able to comment out the call in question, as shown below, and it now works.

spreed/lib/Settings/Admin/AdminSettings.php#506

Please report to ghcr.io/wonderfall/nextcloud:25 .
We have to be able to check whether we can use a function. Having extra stuff in place that throws when trying to find out if a function can be used is nothing we can work around

Ok, thank you!
