Whenever I try to open a niagara system that uses a Lightweight emitter, or anything that references a Niagara System that uses a Lightweight emitter in UE 5.7.1, it causes the engine to crash. Here’s the crash log:
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000480

They worked perfectly fine in 5.6. I tried converting my Niagara Systems to standard emitters, but I can’t package my project because there’s a lightweight Niagara System somewhere and I can’t find it. Not sure what to do here.
