Some of my workspace Git repositories no longer show up in my VS Code Source Control View. Why? How can I restore them to that view?

I have a bunch of repositories that I'm working in by using a workspace. I discovered last week that (as far as i know) 2 aren't automatically opening anymore in source control.

I do see them in my explorer tree and can open them in a separate window from which I can use source control. But needing to open a new window every time for these repo's defies the purpose of my workspace...

Went through all places were settings are set and did a global search to check if these were added to the ignored repo list (git.ignoredRepositories) but they aren't in there.

I also deleted the repo's and cloned them again, but the same issue still persists.

The outcome I expected was to find the 'problematic' repo's somewhere in my config to be ignored, delete that and have every repo in my source control again.

I'd suggest that you check if you closed the repositories (see also my answer post in How can I ignore a whole git repository in Visual Studio Code? for info about that feature). You can reopen closed repositories by using the Git: Reopen Closed Repositories... command in the command palette.

You already mentioned that you checked your git.ignoredRepositories. I'd also suggest to see if you've done anything with your git.autoRepositoryDetection, git.scanRepositories, git.repositoryScanIgnoredFolders, and git.repositoryScanMaxDepth settings that could be causing this.

Note that a change was made to this feature in VS Code 1.80 to improve persistence of whether a repository is closed.
