1. Check if the Issue Occurs in All Projects:

Create a new project and see if the problem persists. If it does, it’s likely a Unity or macOS compatibility issue. Try installing a clean, updated version of Unity or try updating your macOS.

Assuming it's a project specific issue...

2. Delete the Library Folder:

Close Unity, navigate to your project folder, and delete the Library folder. Reopen the project, and Unity will rebuild the folder, which often resolves most issues.

3. Remove Plugins or all Editor Scripts/Utilities:

Some plugins or custom editor utilities might be running and causing these issues. Take a backup of the project and then remove all editor plugins and scripts in editor folder to find out.
