It seems the editor crashes when adding a new Macro to a Blueprint Macro Library. This only occurs if you rename the macro that gets automatically created when you open the macro library to something other than the default. If you leave the name as NewMacro_0, it will not crash. I don't believe the parent class of the Blueprint Macro Library matters as I tried both Actor and Player Controller and I saw the same result.
Tested in //UE5/Release-5.0-EarlyAccess @ CL 16682836 and this did NOT occur, so marking as a Regression.
RESULT:
The editor crashes
EXPECTED:
The editor doesn't crash when adding a new macro after renaming the first macro
