Failed to sign a transaction with Trezor one

[HanZYH]

Hi, I used Trezor one to create a standard wallet in Electrum 3.3.8 downloaded on electrum.org with Win10 laptop.
When I send bitcoin to someone and enter my pin code, there is a error window pop out with hex string that I can not read.
here is the string:
b'\x97\xb2C\xf7\x13\xe3fYFO?\xa7\xd9\xado<\x9a\xeba\xf3\xe70\xcb\xa7\xf1\x9f9H\xa0\xf5\xe4U'

And my Trrezor one just stuck on signing transaction page.
Sorry I can not put a pic here.

I will appreciate it if you can help me out of the problem, so that I can get my bitcoin out of the wallet.

that is probably because you upgraded your trezor firmware.
their firmware was upgraded after a security issue was discovered.
Electrum 4.0 will have the required changes and there will be a release candidate soon

Thank you so much.
Can you provide the version number of trezor firmware? Maybe I can upload the order firmware to my trezor one.

And when you ready to release Electrum 4.0?It's pretty exciting！！！

Already fixed in Electrum #6198
