TMS320F28388D: Projects in workspace are not recognized

Part Number: TMS320F28388D
Other Parts Discussed in Thread: CCSTUDIO

I have some projects I have been working on in a Linux workspace which is not the default workspace (~/workspace_theia). I have about ten projects in the workspace. I recently switched to another folder and created some projects there. When I switch back to the original workspace using File -> Open Folder..., some of my projects are recognized as projects and some are not. Right-clicking some of them gives a Build Projects option while right-clicking on some others does not; they appear to be seen as regular directories and not projects. I have deleted the following directories.

[USER HOME]/.config/Texas Instruments/CCS/.ccs-server

[USER HOME]/.TI-trace

[WORKSPACE FOLDER]/.theia

I am running CCStudio 20.4.0.13__1.10.0. This issue appears to be related to this one.

What else can I attempt to get my original projects recognized as projects again?
