Thank you for reporting a bug to Unity. This issue will be fixed in an upcoming release. We have reviewed the issue carefully, and in this case, the team is unable to prioritize backporting this bug to existing releases. There are a number of reasons we make this decision, including the impact and severity of the issue across our user and customer base, and the possibility that a backport may destabilize a release in production. Today we will be closing this port. Thank you again for taking the time to report this issue, and please let us know if there is anything else that changes the impact or severity of this issue.

Steps to reproduce:

Open the attached project

Observe that the Project window is locked

Close the project

Create a new project (URP 3D Template was used for testing)

Observe the Console window after the new project launches

Actual results: NullReferenceExceptions are spammed in the console until the Project window is unlocked

Expected results: No errors are thrown or a clear explanation is given to the user that the Project window should be unlocked

Reproducible with versions: 2022.3.60f1, 6000.0.43f1, 6000.1.0b11, 6000.2.0a7

Tested on (OS): mac OS 15.3.2
