Were you able to go through the article, use it to troubleshoot the issue(s)
& then if still at a brickwall, start into macOS Recovery to use Disk Utility..?
From there, you'd have options which include erase and install a new OS
as one of the nuclear solutions. If nothing else, you'd be busy waiting for
any of those steps to complete. ~ Or your Mac might have a bad drive.
These are options one may arrive at by following instructions in this article.
• If your Mac starts up to a question mark - Apple Support

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.
