I don’t have a clue what is

f:\dd\vctools\crt\crtw32\dllstuff\crtexe.c:618

Don’t even have ‘F’ disk.

Seems like similar reported:

The callstack is misleading, because the MessageLog simply forwards a log message that is marked as ‘critical error’, which then causes the crash handler to kick in.

The actual error is here:

Critical Error PlayerState /Game/Level/UEDPIE_0_Start.Start:PersistentLevel.PlayerState_3 Object from PIE level still referenced. Shortest path from root:    (Object is not currently rooted)

I will assign this to our Game Framework team.

Hi ,

Have you referenced PlayerState within your custom code?
