Unable to generate key ecdsa-sk/ed25519-sk in Cygwin

Hi,
I'm trying to generate a key in Cygwin with OpenSSH (OpenSSH_8.7p1, OpenSSL 1.1.1f 31 Mar 2020) but my SoloKeys Somu are not detected by the ssh-sk-helper.

$ ssh-keygen.exe -v -t ecdsa-sk
Generating public/private ecdsa-sk key pair.
You may need to touch your authenticator to authorize key generation.

Using solo cli tool the key is detected, (wink and verify works)

$ solo key version
4.1.2 locked

Unplugging the SoloKeys and using a Yubico the ssh-keygen generates the keys.

Same result with a SoloKeys Tap with:

solo key version
4.1.5 locked

I see the same with

Git Bash 2.35.1.2

Same here.
