This happened to me as well just now. I figured out what the problem was although i don’t know if you have the same problem. My issue was that i used the “standard wallet” when first using yoroi, but never after that. months later i forgot all about the standard wallet. Go to trezor Suite and go to the standard wallet. when it asks you for the passphrase in Yoroi, don’t type anything on the Trezor (just hit “ENTER” on the PC, which is what you do for non passphrase (non hidden) trezor accounts). That worked for me, hope it does for you
