UPDATE :
After enable WSL version 2 (wsl --set-version debian 2) i can finally generate an ecdsa-sk keypair :) !
Unfortunatly i still can't generate ed25519-sk keypair. I don't know if it's possible with windows-fido-bridge as you didn't put an exemple in the readme.
Maybe it can be useful to precise that.
There is the output when i try to generate ed25519-sk :
WINDOWS_FIDO_BRIDGE_DEBUG=true SSH_SK_PROVIDER=libwindowsfidobridge.so ssh-keygen -t ed25
519-sk -v
Generating public/private ed25519-sk key pair.
You may need to touch your authenticator to authorize key generation.

Glad you were able to get it working! I personally use WSL2 exclusively, so I'm not terribly surprised it doesn't work on WSL1. That said, I can set up a WSL1 distro and see if I can get a repro; if it's a simple fix, I've no problem supporting it.
And yeah, unfortunately, of the algorithms supported by OpenSSH, Microsoft's WebAuthn API only supports ECDSA: https://github.com/microsoft/webauthn/blob/master/webauthn.h#L161. I can add a note mentioning that in the README and print a message if one attempts to use it.
I'll reopen this for now to remind myself to take a look sometime over the next few days.

Hmm, I tried making a WSL1 Debian bullseye installation and it worked with no problems using the current latest windows-fido-bridge from apt.mgbowen.dev. Unfortunately, I don't have much more to go on without better debug logging, which is on my todo list.

Added explicit logging about ed25519-sk being unsupported and updated the README with info about the same in this commit.
I'll go ahead and close this now. If you have any issues in the future, please feel free to open another!
