Extension does not work inside workspace

[whoami730]

When a multi-folder workspace is opened, the extension errors with "Working folder not found, open a folder and try again" - despite a folder being open in the workspace.

I found the same, I have to switch to opening just a regular folder in vscode (not a workspace) when I want to use this extension. The reason I use a workspace is i'm debugging a project with multiple pybind libraries, built using CMake, and I want to be able to build all the separate cmake projects in one vscode instance
