Reproduction steps:

3. Resize the Scene or Game view windows for about 10 seconds
4. Observe the Unity Memory usage in Activity Monitor or Task Manager
5. Resize the Scene or Game view windows for about 3 minutes

Expected result: No memory usage increase and the Unity Editor does not crash
Actual result: Memory usage increases and eventually the Unity Editor crashes

Note:
-Issue reproduction on the 2023.1 stream is inconsistent

-Issue is reproducible with a fresh new project and is not linked to the attached project
-On macOS console errors “IsCounterSamplingSupported: Unsupported MTLCommandEncoder protocol” appear before the crash
