I have fortunately not encountered this. Here are some things I would try to work around this (assuming it is too much work to restart).
Change the loop point. Assuming it is at 0 right now, make it 00:00:01 to see what happens. Maybe that will ‘kick start’ the buttons.
Copy and paste the menu and use the second one.
If the above doesn’t work, then have your first one auto-activate to the second one.
Have a dummy black 1 second menu screen as your first menu which times out after 1 iteration to your next menu screen.
