Hi,
Have you made any changes to the pc or the USB?
Please try to use the command line"repair-bde -RecoveryKey Volume:PathToRecoveryKey " to repair the BitLocker and use the command "manage-bde –unlock F: -recoverykey "G:\Backupkeys\recoverykey.bek" to have a test.
If the issue persists, please check the Event Viewer for any related error messages to troubleshoot this issue.
For your reference:

Sometimes, BitLocker encrypted drive can be unlocked with correct password or BitLocker recovery key on another computer.
Hope above information can help you.
