Jade blockstream stopped working

[evgeniy-emelyanchyk]

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:

qt.qpa.window: <QNSWindow: 0x7fe65a0b25d0; contentView=<QNSView: 0x7fe65a0b21d0; QCocoaWindow(0x6000039fb180, window=QWidgetWindow(0x6000024e1380, name="QPushButtonClassWindow"))>> has active key-value observers (KVO)! These will stop working now that the window is recreated, and will result in exceptions when the observers are removed. Break in QCocoaWindow::recreateWindowIfNeeded to debug.

During handling of the above exception, another exception occurred:

Electrum version is 4.5.5 Jade hw have the latest firmware 1.0.30

I can't reproduce this issue - was it resolved ?

4.5.5 is still latest, and I can confirm I know (other) users experiencing this issue.

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: [...]

  File "electrum/plugins/jade/jade.py", line 287, in sign_transaction
    multisig_name = _register_multisig_wallet(wallet, self, txout.address)
  File "electrum/plugins/jade/jade.py", line 64, in _register_multisig_wallet

TypeError: fromhex() argument must be str, not None

If you go to menubar>Wallet>Information, and you click through the keystore radio buttons, it shows the "BIP32 root fingerprint" at the bottom. Is it "unknown" for that/any keystore?

I can confirm I know (other) users experiencing this issue.

Which issue specifically? I mean, the two tracebacks in OP look unrelated. Also, I just tested wallet creation and tx signing across a bunch of platforms and configs, and did not see problems. Not sure how to narrow down the specifics, but more details to reproduce would be useful.
