Steps to reproduce:

Open a Unity Project
From the Asset Store, add Unity Learn 3D Game Kit to your assets (any complete project should also cause it but 3D Game Kit is very compatible with nearly any Unity Version without issue, so makes reproduction easier if regression testing)
In the Unity Editor, open Package Manager via Window > Package Manager and download the 3D Game Kit asset in the My Assets section
Click 'Import x.x.x to project' and make sure to click the 'Switch Project' option in the pop-up that appears
Wait for the new temporary project to open (this could take a few minutes)
Open the Start scene at Assets > 3DGameKit > Scenes

Actual results: The Console has many errors from certain assets not being found.

If you enter playmode, the console will get 61 warnings, all from missing scripts, as well as errors for missing animation receivers. Because the scripts are not imported, clicking on the Main Menu options Start and Exit Game, for example, will do nothing.

Expected results: All assets are imported correctly.

Reproducible with versions: 6000.1.0a6, 6000.0.29f1, 2022.3.52f1, 2022.2.0b6

Not reproducible with versions: 2022.2.0b5, 2021.3.46f1

Can't test with versions: -

Tested on (OS): Windows 11

Notes:

When importing directly into the initial project (and not using the switch project functionality), it imports all assets correctly. It is when using the switch project functionality to create a temporary project for the complete project where the bug arises.
This bug was reproduced on multiple of Unity's complete projects from the Asset Store: 3D Game Kit, Dragon Crashers - UI Toolkit Sample project, Tanks! Tutorial, Lost Crypt - 2D Sample Project
This is only reproducible in Windows 11, it's not reproducible in Windows 10, Mac, or a virtual machine.
