[Bug]: Unable to add or sign Trezor account in v12.1.1

[plasmacorral]

Describe the bug

Was working on a migration test from 12.1.1 to RC 12.2.0 and noticed that I was unable to add a Trezor account. If I add a Trezor account in a version prior to 12.1.1 I can add the Trezor address, but after migration to v12.2.0 RC 8fa9cc090c2804d0dd5e3448e9d1b25eb958833e I am not able to sign, send, or add more Trezor accounts.

Confirmed that 12.0.6 and 12.1.0 do not have this issue, but 12.1.1 and 12.2.0 are impacted.

This was observed with a Trezor Model T running firmware 2.8.1 on a Mac running Sonoma 14.6.1.

Expected behavior

When using a Trezor address a pop-up window is opened and can communicate with Trezor.

Also, should not show a Ledger Live related error in yellow text while trying to add Trezor.

Screenshots/Recordings

12.1.1: Not able to add the device (or sign if address was present from migration from MM <12.1.1) Recording

12.1.0: Able to send/sign in Chrome Recording

Steps to reproduce

1. Configure a wallet and get to wallet view
2. Tap the account
3. Tap Add account or Hardware wallet
4. Tap `Add hardware wallet'
5. Tap Trezor
6. Note pop-up opens, but green spinner

I am able to reproduce this locally as well. It works on v12.1.0, fails on v12.1.1.
