There are some clear ideas here:
• If your Mac starts up to a Question mark - Apple Support
https://support.apple.com/en-us/HT204323
"A folder with a 'flashing question mark' means that your startup disk is
no longer available, or doesn't contain a working Mac operating system."
The answer has two-parts, first is easy; second half below, is more involved:
"IF the question mark persists, follow these steps:
- Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.
- Turn on your Mac and immediately press and hold Command (⌘) and R to start up from macOS Recovery.
- While in macOS Recovery, use Disk Utility to repair your startup disk.
- If Disk Utility found no errors or repaired all errors, reinstall macOS.
- If you still need help, please contact Apple Support."
