This article may have something about that here:
• If your Mac starts up to a circle with a line through it - Apple Support
//support.apple.com/en-us/HT210901
"A circle with a line through it means that your startup disk contains a
Mac operating system, but it's not a macOS that your Mac can use."
[from this page • If your Mac doesn't start up all the way - Apple Support]
"Learn what to do if your Mac starts up to a circle with a line through it (prohibitory symbol)."
- Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.
- 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.
