Studio-3T does not start

Hello, for some time the start of Studio-3T breaks off with the following message. Can someone help me?

Gdk-CRITICAL ...: gdk_threads_set_lock_functions: assertion 'gdk_threads_lock == NULL && gdk_threads_unlock == NULL' failed

What platform are you running on?

OpenSuse 15.3


Well, in the process of looking at the problem, it seems the underlying issue (a bug in Webkit) was sorted out and pushed out to various distros. I have OpenSUSE Leap 15.4.1 running here with the latest updates and Studio 3T is now happily running. I’d invite you to have another try and see if the issue is resolved on 15.3.
