Reproduction steps:
1. Open the attached project ("ReproProject_96077")
2. Open scene "Scenes/SampleScene"
3. Enter and Exit Play mode around 5 times

Expected result: The Editor either freezes or crashes
Actual result: The Editor enters Play mode

Reproducible with: 1.8.19 (2022.3.61f1, 6000.0.46f1, 6000.1.0b14, 6000.2.0a8)
Oldest version checked for regression: 1.6.0-pre.2 (2022.1.0a1)

Reproducible on: Windows 10 (User), macOS 15.3.2 (Intel)
Not reproducible on: No other environment tested

Notes:
1. The Editor would sometimes freeze/crash on the first try. Other times, it took 3 Play mode enter/exit cycles.
2. Errors/Stacktraces:
NullReferenceException: Object reference not set to an instance of an object
