Can't push with SSH under R 4.2 on Windows 10

[jonathan-g]

Short description:

Under R 4.1.3, I can push to github with SSH transport using git2r::push()

Under R 4.2.0 on the same computer, git2r::push() fails with

Error in git2r::push(".", name = "origin", credentials = cred, refspec = "/refs/heads/main") : 
  Error in 'git2r_push': Failed to retrieve list of SSH authentication methods: Failed getting response

Code to reproduce :

import(git2r)
cred = cred_ssh_key(publickey = "~/.ssh/id_ed25519.pub", privatekey = "~/.ssh/id_ed25519")
push(".", name = "origin", credentials = cred, refspec = "refs/heads/main")

The remote repository has URL "git@github.com:<username>/<repository>.git

This code succeeds under R 4.1.3 but fails under R 4.2.0. I have freshly installed git2r under R 4.2.0.

I'm still seeing this error with R 4.2.1.
