I can confirm this. If either deck or circles is disabled, then it works again, but having both apps activated together produces the problem for me.

Also, there is the error message Error: Call to a member function getUID() on null in the logs. I think it’s related. The issue has also been mentioned here: Error: Call to a member function getUID() on null in Circles.php:202 · Issue #560 · nextcloud/circles · GitHub

lfajardo · March 5, 2021, 12:55pm

Same happens to me. I have deactivate Circles as a temporary solution.

nc_user_210304 · March 13, 2021, 8:12am

After recent updates of both apps this issue is gone.

stefan-niedermann · March 13, 2021, 8:28am

Yes, quite a lot has been done in recent versions to improve the support for the circles app.
