Update - tried restarting again and it didn’t work still, did a full system restart and still didn’t work. Reformatted the 64g Tesla stick and it worked. Lost all my footages but at least it works now. I’ll wait and see what happens the next time I drive. Hopefully it’s fixed.
Glad it worked for you. Maybe I formatted it then forgot, but it seems like the holiday update has mostly fixed it for me.
