gitcreds_set() appears ineffective

[RossBoylan]

Problem

gitcreds_set() doesn't seem to be setting anything:

> gitcreds::gitcreds_set()


? Enter password or token: ghp_XXXX
-> Adding new credentials...
-> Removing credentials from cache...
-> Done.
> usethis::gh_token_help()
* GitHub host: 'https://github.com'
* Personal access token for 'https://github.com': <unset>
* To create a personal access token, call `create_github_token()`
* To store a token for current and future use, call `gitcreds::gitcreds_set()`
i Read more in the 'Managing Git(Hub) Credentials' article:
  https://usethis.r-lib.org/articles/articles/git-credentials.html
> gitcreds::gitcreds_get()
Error in throw(new_error("gitcreds_no_credentials", url = url)) : 
  Could not find any credentials

Trying gitcreds_get in a new session later yields the same result

Background Information

Based partly on questions developers asked in a somewhat similar bug, I installed oskeyring and collected additional info:

> gitcreds::gitcreds_list_helpers()
[1] "manager"      "manager-core"

> gitcreds::gitcreds_list()

R version 4.3.1 (2023-06-16 ucrt) git version 2.43.0.windows.1 gitcred 0.1.2

So both RStudio and R are a little behind current.

I have accessed github in various ways, including ssh, from various applications. In Windows Credential Manager (under Windows Credentials | Generic Credentials) I see at least 5 entries associated with github.com, 3 of which were last modified today. I also see that Windows and Certificate-Based Credentials both say "have been disabled by your system administrator".
