ref: Three long beeps, three short, then three long

To resolve a firmware issue, your Mac is restoring its firmware. You might see a progress bar, after which your Mac should start up normally. ref: https://support.apple.com/en-us/HT202768

It sounds like the firmware update was interrupted or is failing to install—which could point to a hardware issue, either RAM, SSD, or logic board...

I would contact Apple directly and see what they recommend:

Call Customer Support  (800) MY–APPLE (800–692–7753)

or on line  https://getsupport.apple.com/

Outside the USA—Contact Apple for support and service by phone

See a list of Apple phone numbers around the world.

You can try a SafeBoot if it will allow you to proceed:  SafeBoot https://support.apple.com/en-us/HT201262

You can try First Aid from Recovery, if it will allow you to proceed:  Recovery: https://support.apple.com/en-us/HT204904

Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities>  Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur) If errors are found and repaired, run again until no errors reported.

Disk Utility>View>Show All Devices The best sequence is —

• Volume level
• Container level
• Parent drive
