*Steps to reproduce:*
# Open a Unity Project
# Add a complete project to your assets (e.g. Dungeon Crashers - UI Toolkit Sample project: [https://assetstore.unity.com/packages/essentials/tutorial-projects/dragon-crashers-ui-toolkit-sample-project-231178)|https://assetstore.unity.com/packages/essentials/tutorial-projects/dragon-crashers-ui-toolkit-sample-project-231178]
# Open the asset in Unity
# Download the asset via the Package Manager
# Click 'Import x.x to project' on the asset in Package Manager. A pop-up should appear telling you that importing a complete project will overwrite your current project settings
# Click 'Switch Project'

*Actual results:* The current project closes. A new 'temporary' project is not created.

*Expected results:* The current project stays open and a new 'temporary' project is created and opened (this is how it works on Win 11).
