'Why are some folders missing when I switch from "folders view" to "solution view" in Visual Studio 2019?

I have cloned a repo in Visual Studio 2019 and whenever I try to open the repo using the "open local folder" option, the folder view loads, here I can see all the projects in the repo but as soon as I switch to the "solution view", a few of my projects and folders go missing. I have tried to right click and add the project again to the solution but as expected, it throws an error saying the project already exists. What am I doing wrong? How can I fix it?
