4365 and 4366 both immediately crash on startup for me. I never even see anything except the frame.
My understanding is a fix is in progress.
Build 4367 should fix this. Also - some code was added to detect cases where a deadlock occurs - this is usually where you see a white overlayed screen and Interface is non-responsive. It looks like it can take up to 10 seconds to detect this then trigger a bugsplat report. I’m training self not to close out Interface if it enters this condition now.
