I have 2FA setup by my organization on GitHub.com. I can see all the projects, but as soon as I type anything in Search (when trying to add repo), red icon appears over my account with ToolTip "Unable to read repositories... Validation failed"
I am having the same issue.
ST version 3.3.9
I can see the list of organization repos and "load more button" works, but search does not work - as soon as I type something existing the list gets and does not recover until I remove all contents from the search-box. The list is empty even if I type in full existing repo name.
On the firs picture there is "blog" repo (the first one).
But when I type it in - all blanc. And I have a red mark on my portrait, whatever that means.
I can't reproduce this at the moment, I'm assuming you using the OAuth authentication option, rather than Basic Auth?
Again I'm assuming you get a green confirmation that your credentials are OK in the Tools/Options/Authentication tab when you edit the account?
