Multiple github accounts not working on SourceTree

[TaSeeMba]

I recently added 2 github accounts to my Windows SourceTree and cloned 2 repositories. Pushing and pulling from the first repo suddenly stopped working. The error given was:

remote: Repository not found.
fatal: repository 'https://github.com/xyz/' not found

I managed to get around the problem by uninstalling and reinstalling the credentials manager using:
$ git credential-manager uninstall
$ git credential-manager install
