Hey DrCally1!

I definitely appreciate why this situation would be concerning to you. Let me see if I can offer some suggestions to help. To get things started in the right direction, we actually have a great article that explains the question mark folder you're seeing, as well as how to address it; check that out here: If a flashing question mark appears when you start your Mac - Apple Support

Do me a favor and try each recommended step, but make note of the results so you can keep me updated in case the article itself doesn't square things away. Cheers!
