When Editor reload is on and user both hot reloads changes and tries to enter play-mode, editor crashes

More details from user: (needs confirmation)

it looks like if I recompile when it's not running (by using the shortcut of Fast Script Reload) and very quickly I use the shortcut to Play/Start by game, but the compilation has not finished, then it crashes Unity. (For info I use a Mac). I understand that it cannot run if the compilation is not finished, but sometimes I go too fast, and this happens. It would be good if it could just prevent to play instead of crashing Unity.

Reproduce in the Unity editor on macOS by triggering Fast Script Reload and immediately entering Play mode before compilation finishes. Confirm the crash behavior and trace the reload/play transition; done means Play mode is prevented safely while compilation is still running instead of crashing Unity.
