You should use another browser and warm up before using. This will help you limit errors like you are currently experiencing
 
Continue using your account on that device, it should be good at some point later on. Also, try not to keep changing devices with the account, at least for now.
 
its because you're using the account on a new device.
you will have to keep using the account for 2-3 more days on same device, same proxy and try again.
 
Some of problems who they will prevent to active 2fa

Your cash browser
Your browser isn't update
Your proxy is not clean ( Chang it to solve)
Your verification of account isn't completed ( check your phone number)
 
Facebook needs time to verify information to accept changes. So Give it time and try again Next time
 
If possible, perhaps you can temporarily disable two-factor authentication from your account settings
 
Facebook needs more time to verify information and accept login changes, wait some time before trying again. Or try changing your proxy or VPN: If you're using a proxy or VPN, turn them off and try logging in again. Facebook may feel suspicious if you visit from unusual locations.
I would suggest you give it a little time then try again later.

If it doesn't change, try using many different network IPs
