Earlier this week, I went to open one of my VS Code workspaces and only five were showing. Usually I have about 30.
So I worked around it for a few days and today I took the time to figure out what was going on.
I’m running version 1.65.2 of Visual Studio Code.
What I discovered is my workspaces with an period in the file name were the ones that were hidden. For example, campbellsoup.ca.code-workspace was hidden.
Deleting the extra period brought it back in the workspaces sidebar.
