Baikal version: 0.9.4

Expected behaviour:
Sync

Current behaviour:
No Sync

Steps to reproduce:
After Upgrade to php8.2.7 and baikal-0.9.4, I can still log in the web interface and I see there all calendars and all address books there, but I can't sync any more. I get this failure:

Guess I have the same problem.
Didn't see anything was going wrong until I changed my smartphone and couldn't get the phone to sync via DAVx5.

So I tried to login via firefox on my pc. Not possible either.

This only happens with existing users. When I create a new user, login is possible via webbrowser and also via DAVx5.

Seems like this issue was reported in 2015 for owncloud calender, too. But couldn't find a solution yet.
