Binary (Installed Build)//UE5/Release-5.1 @CL22986940
I encountered this same crash when creating a landscape twice, but was not able to consistently reproduce it with those steps. I figured out that I could get this crash to occur much more frequently (5/6 repro rate) with the steps listed above.
Regression tested against Binary (Installed Build)//UE5/Release-5.0 @CL20979098 where the issue does not occur. Marked regression as Yes.
Expected Result: Value of the Max LODLevel is changed without issue.
Actual Result: Editor crashes after the value change.
