KDENLIVE crashing because of permissions issue

For about a week, since last update, I cannot start the application at all. I am running Fedora 38 but this also happens on 37.
This is the trace when I start it from terminal:

This clearly is a permissions issue because if i change user ID for current user to “0” (root) or run KDENLIVE with sudo, the application works fine. There are some issues in the traceback, but I have no problem opening, creating or editing projects. Naturally I do not want to be logged in to GUI as root and run applications.

Could you explain when Kdenlive crashes to understand the issue correctly?

When I am logged in as a normal user, I try starting KDENLIVE and it doesn’t start. It will just hang on the flash screen. If I start it from CLI, it will produce the error I attached. Interesting thing is also that it seems to complain about: “qrc:/qml/timeline.qml:497: ReferenceError: proxy is not defined”
timeline.qml is a part of SHOTCUT installation, not KDENLIVE.
As I said, if I start KDENLIVE as root, it runs fine, but I do not want to run any applications as root.
