You missed an important step:
run Tor service on your PC/device where is trezor suite installed.
Exactly in the connect wallet - electrum are very clear instructions but you ignore them.
Also you can skip Tor onion address and just use your local IP of your node if you use that device in the same LAN.
My honest opinion: don’t use that trezor suite, but connect your trezor HW to Sparrow and/or Electrum wallet app as interfaces for your HW.
