I have two companies.  One seems to stay open but the second crashes.  After opening the file it just shuts down.  I can spend countless hours on this Sunday evening and go through all of the various troubleshooting steps in this thread but I'm wondering if because it is my second company if that is a clue to something specific.  I updated several weeks ago to Desktop Pro Plus 2022 and everything has worked until today.  My version is R5-45 (I have it set to automatically update but it didn't offer to update to R5-50).
