Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.102.1
• OS Version: Linux x64 (Ubuntu 25.04)

Steps to Reproduce:

1. Open a workspace with at least one git repo with a private remote on Github and Git:Autofetch set to true
2. Watch the Output window for Git and at some point a message similar to this will pass:

2025-07-23 10:56:36.473 [info] Missing or invalid credentials.
Skip silent fetch commands
Missing or invalid credentials.
Skip silent fetch commands
remote: Repository not found.
fatal: Échec d'authentification pour 'https://github.com/xxx/xxx.git/'

Manual fetch does work without a hitch but it is annoying when having to remember that some remote repositories changes are visible automatically while others need to get fetched/verified manually each time...
