Source-checked About 10 minutes
Answer
Update Messenger, verify the Facebook account can sign in on the official website, restart the iPhone, and use Facebook's account-recovery flow for password or security blocks.
Update the app
Install the latest Messenger version from the App Store and confirm iOS has enough free storage.
Test the account safely
Sign in at facebook.com in Safari. If that fails too, use Facebook's official password and hacked-account recovery tools.
Restart the app and iPhone
Force close Messenger, restart the iPhone, and retry on a reliable network without an unknown VPN.
Reinstall last
Delete and reinstall Messenger only after confirming account access; never give a login code to a person or unofficial support page.
