Locked my MacBook Pro using Find My and wrong codes

Hello everyone. so I locked my laptop using find my but my nephew at home entered the wrong code multiple times until the laptop locked and it said wait 60 minutes until you try to enter a code again. however. after 60 minutes it just says wrong code try again later without any time without giving me the option to enter the code generated by find my again. it's been a year now since this happened and I still have the same issue. on iCloud website in find my the device is showing stolen and cannot be found. I cannot connect to the internet on the laptop nor can I do anything other than switching it OFF or restart or sleep. please pay attention that after waiting 60 minutes I do not get the option to enter a code, it just says wrong code try again without time.
