After inserting Nitrokey I get the message ’ There is no default boot option configured yet. Would you like to load a menu of boot option? Otherwise you will return to the main menu’.

When I hit Yes, I want to configuire boot menu I get error TOTP 236262 Error checking code, insert Nitrokey,
It is in Loop.
I want to make default boot.
It shows error and comes back to the main menu saying ‘There is no default boot menu’.
