Edit: yes in my opinion, I think that sd card reader issue is what is causing your problem.
-Before I had read you reply:
Is it a wiikey or wasp? On my wasp I initially tried using it without the sd card reader and it had caused my wasp to not initiate. Once I had plugged it back up it then froze on the init part, but then randomly started working a few days later.
I then had another problem where the wasp was not getting a clean enough connection to ground that would cause the wasp to sometimes not show the sd card and its contents. It would show that menu you explained
