If you disable Support PointLightWholeSceneShadows and try to place a point light in a level the editor will crash.
Current work around is put shadows to low from engine scalability settings.
Working as expected in 4.19 CL# 4033788
Found in 4.20 CL# 4212847, 4.21 CL# 4229165
This is a regression.
Results:
Editor will clash
Expected:
The point light will be placed in the scene
