Opening a project in QDS opens it in QC view

Issue found

• When I open the DS, and a project, it opens in Creator view. This also happens, if I open something else than QML file. 
• See video: DSgoesCreatorSnap2.mp4
• Snapshot:  2 (24 Nov 2023)
• MacOS, M1

How to reproduce

1. Take the latest snapshot
2. Open DS
3. Open an existing project
4. The project opens up in Creator view, as the puppet fails. This usually happens on first run of the day. Second run it may not happen.
5. Also, if I open a project, which has some other files than QML. Attached is the project that I had in the video

How it is expected to work

• Design Studio should not show Creator UI.
