I really wished you'd answered more specifically, with the full name of the products. When I go and check the current versions at Adobe.com, they list:
1, Lightroom Classic - v13.1
2, Lightroom - v7.1
So, it seems you want to import these "missing" images into your Lightroom Classic catalog, where somehow they exist / are known only to the browser-based Lightroom. Questions:
a, Do you consider your Lightroom Classic catalog, the local-installed software to be your 'master' version of all images files and editing, Y / N?
b, Do you even use the browser version of Lightroom Y / N?
c, What image format do you shoot in? What format are these files? RAW, JPEG, other?
I don't use the browser Lightroom version. It seems files loaded there are storage in the cloud, with no way to get to the underlying (original) images except via the browser-LR. Personally, I'd access the LR-browser and export those images as DNG, as suggested before, setting the target output to a local disk on your computer, the same place where you store all your other images. Then, I'd access LR-classic and import the images and consider the problem solved.
You might open a technical support chat with Adobe and ask the same 'how' question and see if they have a better idea, maybe having them remote into your system and see more of the specifics of the issue.
