I got my new Trezor model t in the mail the other day. I set it up right away-no issues at all. Now after a few days I wanted to begin initiating a transfer and a red fatal error message keeps popping up after connecting. I don’t have a second laptop or and already tried a different cable but nothing is working. Please help! Thank you!
