FVE_E_REBOOT_REQUIRED

FVE_E_REBOOT_REQUIRED means that the requested BitLocker operation has reached a point where a system restart is required before it can continue. This can occur after a configuration or protection change that must take effect during boot.

How to investigate

Confirm that a valid recovery method is available before rebooting, especially after changing boot, TPM, or protector settings.
Complete the restart and then use status information to verify the requested state change.
Avoid launching another conflicting BitLocker operation before the restart workflow has completed.
