If you're "running as a full node" then your full node is the remote node for a hardware wallet, isn't it?. I'm confused. I've only ever used the CLI which provides separate applications for wallet and node, and I connect the CLI wallet over RPC to my local (full) node. My understanding is the GUI works the same way while only presenting the one interface to the end user. But you should have a monerod running under the hood.

No the hardware wallet is only used to sign the transaction that's broadcasted by my local node. The failing case was with monerod in the background.

Maybe I should look into the CLI. Does it support Ledger?

The CLI does support Ledger but it uses the same monerod binary as the GUI.

Did you export your view key with Ledger? If you refuse it can cause hanging and crashes. With exported view key and the latest version there shouldn't be any of the issues you are describing.

CLI supports Ledger, just need to have it plugged it at the time

Haven't had any issues on MacOS using monero-wallet-gui.app and a Ledger Nano X.

I'm on Windows. That might be the reason.

Did you open an issue? There is no known bug like you are describing regarding hardware wallets and full nodes.

“users not reporting issues they have” is annoying. Maybe projects (crypto especially) should offer pizza money level rewards for reporting any valid bug
