Same issue here, it started for me during the developer beta and never went away. I was also getting the error about "post-quantum key exchange". I upgraded my git server (a little docker container running the default git and openssh setup) and the warning went away. Xcode still hangs on pull/fetch though. I can push without issue. I can pull from the command line without issue.
