I switched my proxy client from ssr to clash for windows for some reason. Then I got an Error prompt of DNS changing of github.com in known_hosts while using git clone.
So I deleted the item and git clone again, still failed. Then I re-generated a ssh key pair through ssh-keygen -t rsa -C "my-comment" and stored on github->settings->SSH keys. While testing ssh -vvvT git@github.com, it required password of git@github.com.
Here's the debug output:

git@github.com's password:
My Envs with SSH keys configured:
- Windows 11 (Fail, requiring password) [OpenSSH 8.1p1].
- WSL2 Kali on Win11 (Fail, requiring password) [OpenSSH 8.7p1].
- Ubuntu18 VM (Success with ssh -T git@github.com) [OpenSSH 7.6p1].
I also tried to scp UbuntuVM:~/.ssh/id_rsa* Win11:~/.ssh/ and test with ssh -T git@github.com, but it still failed with password requiring.
I'm really confused. :(
