Samsung galaxy a52 locked at restart

[Aaron2563]

Forgotten pattern to unlock after restart says try again in 30seconds 

Not able to reboot it at all goes back to locked screen after trying to reboot it.

Factory reset the phone would be your only option but you probably need to remember your Google account password if you do due to activation lock
