I encountered a crash issue when using the GameplayCamera plugin in version 5.6

Hello! Sorry about the trouble. Are you using the 5.6 Preview build? There are some known bugs in there, and generally speaking Preview builds are known to be unstable… but I haven’t since this crash before.

I can’t reproduce this locally, and it’s hard to tell what’s wrong from your screenshots. Would you be able to post a minidump file, or get the callstack using a local build from source, so we can see where exactly it’s crashing?
