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?
