What version of Electrum are you using? I've heard that some versions are quite buggy with the Trezor so if you're running an older version I'd suggest updating to 2.3.2 and seeing if that helps at all.
I actually use the lastest version

In that case I'd suggest to try and reinstall Electrum. I just tested restoring a Trezor seed through Electrum on Windows, and had no issues in doing so. If that doesn't work, try using an older version of Electrum and hopefully that will solve the problem you've been having.
