lnd: "Invalid address or key" when attempting to openchannel

Background

This is an upgraded 15.1 node with existing channels and chain balances, including pending force closes

Using a btcd direct backend that was upgraded to 22 as required

When attempting to open a channel, it fails with:

[lncli] rpc error: code = Unknown desc = -5: Invalid address or key: bc1p...

Same result with defaults or specifying anchors as chan type.

Addresses in error do not appear to be UTXO’s in the chain wallet

Your environment

• version of lnd: 15.1
• which operating system (uname -a on *Nix) Ubuntu / 5.4.41-1
• btcd22

Steps to reproduce

Expected behaviour

Channel should open and show a txid

Actual behaviour
