Can't sign partial taproot PSBT with connected Ledger hardware

[kusan-thana]

I have same issue than people in issue #883 : can't seem to sign a partial transaction with the sighash type: Single + Anyone Can Pay

The transaction I try to sign:

I think this is the related issue on the ledger side: LedgerHQ/app-bitcoin-new#124

I think the issue in sparrow is that we don't get any result, no popup or message indicating any error after selection the ledger.

Have you checked the Sparrow log file for any errors there?

Yes, I have nothing in the log file.

I click The "Sign" button and the popup disappear and nothing on the ledger device:

If there's nothing in the log file, then HWI is not returning an error response, it's just returning the unsigned PSBT. Suggest you open an issue there: https://github.com/bitcoin-core/HWI/issues
