Jade stop working with electrum

Electrum version is 4.5.5
Jade hw have the latest firmware 1.0.30

I've tried to setup Jade+Electrum multisig 2/2 for BTC Testnet and it was setup without any problem, but when I tried to sign transaction I've got the error:

```

```

Then I try to setup standard wallet electrum+Jade and got another error when I try to sign trx:
```

During handling of the above exception, another exception occurred:
