Steps to reproduce

Hello everyone,

In advance - I am not the sharpest tool in the shed, and propably not as technically versed as I should be.
I have the following usecase:

I want to use ssh signing for github. This does not work with current openssh version built in into windows. 8.1p1.
I therefore go ahead and istall OpenSSH beta with winget as suggested in the manual here.

I uninstall OpenSSH client from optional features and add C:\Program Files\OpenSSH to Path, otherwise ssh -V returns 8.1p1.
I then can successfully sign my commits with ssh keys, which is great.

What is not great, is that then my key based authentication stops working.
I use KeePass, and Keeagent, which seem to continue working -

Expected behavior

I would expect it to login with key as 8.1p1 does.

Actual behavior

Instead, I get a password prompt.

Sorry, not sure what to do here.

Start by reproducing the reported difference between the built-in Windows OpenSSH 8.1p1 client and the beta installed with winget, using the KeePass/KeeAgent setup and version 8.9.1.0. Compare ssh signing and key-based authentication behavior, then document the relevant environment details; the issue names no source file or test, so the affected entry point must first be located.
