I have a customer that, when attempting to open another company file from either the history menu, or by selecting Open Company File from within the app, is immediately booted from the program. There is no issue when opening the same company files by manually navigating to the folder they are in, then double clicking them. When starting QuickBooks after exiting/crashing the program doesn't have any issue opening the most recent company file. The crash only happens if you attempt to open a different company file from within the program.
