Metamask Error: Unknown Address

I set up my Trezor wallet, connected it to Metamask and transferred tokens into it. However, upon attempting to transfer from my Trezor Metamask account the transactions are failing and I am receiving the Error: Uknown Address.

I have taken advice from other posts and connected to MEW to confirm that the tokens are visible there. I believe this may be a passphrase issue, as suggested in other posts. However, i cannot recall using a passphrase.

I have tried not entering a passphrase when attempting a transaction, which has been unsuccessful. Does this mean that i have used a passphrase and need to try guessing it until I remember the correct one?

Thank you in advance.
