The editor crashes when loading a SubLevel with HierarchicalInstancedStaticMeshComponent and SphereReflectionCapture via the levels window.
Working as expected in 4.19 CL# 4033788
Found in 4.20 CL# 4302132 and 4.21 CL# 4328255
This is a regression.
Results:
The Editor will crash
Expected:
The level would load
