Issue when entering design tab.

[katekyy]

Qt Creator Version: 9.0.2
Python Version: 3.10
OS: Windows 10

When I enter into the design tab it's giving me a weird error that I cannot find solution for anywhere. (I am using Qt Quick)
After clicking OK I can normally use it, but it's really bothering me.

There it is:

EDIT: May I add that it's plain new project without anything added, except default code that Qt Creator gives.

The issue seems to be solved when i switched to Qt Creator 10.0.0-beta2.
