If you really need to format the uSD cards, pull them out and put in either a working camera or a PC to format.
HOWEVER, there is almost never a need to format the uSD cards in the cameras. I have 28 Wyze camera - all of which have uSD cards that are set for continuous recording. I think I could count the number of times I have formatted any of them on the fingers of one hand, with spares.
