Thanks,
I did a google search for where it is crashing:
[2023.09.25-16.06.24:899][149]LogWindows: Error: appError called: Assertion failed: !bIsForCompilationOnly [File:D:\build++UE5\Sync\Engine\Plugins\FX\Niagara\Source\NiagaraEditor\Private\NiagaraGraph.cpp] [Line: 3886]
It looks like there are others experiencing this too. ( and one potential solution )
Another troubleshooting idea would be to make a copy of your project and try opening it in 5.3 to see if this bug has been fixed.
