5-0EA Player Location Causing Unhandled Access Violation Crash

Hello, I am working on a level for a video game in UE5 Early Access, and just today began experiencing a strange bug- suddenly an invisible line has appeared across my map, and crossing it will yield an Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000000 crash, referencing UnrealEditor_ApplicationCore. The strange thing is that the location of this crash zone changes based on the location of the player start- if I move the player start to the center of the map, I can traverse it all without any crashes, and if I move it to the side that was previously inaccessible, the crash can be replicated on the original safe side. I have no idea what could have caused this bug- if anyone has experienced something similar, or has any guidance or advice, I would greatly appreciate it.
