Search In feature not looking into certain folders

Hi all,
Windows 11, running Opus 13.5 x64 build 8871
This one has me stumped
When I search for a file *.mp4 after selecting This PC in the Folder Tree, the search does not return files that are in the Videos folder(library that points to d:\videos)
Here are the steps to reproduce.
First note the desired video, Cairo Station, is in the Windows Video Library, Video points to d:\videos

For the search setup I highlight This PC and the enter *.mp4


Not sure it is relevant but when I do that , the Folder tree chances the highlight fr om This PC to to Opus Search Results fpr This PC

Note the search results did not include Videos Cairo Station D:\videos

Searchung D:\ directly returns Cairo station. The problem may be limited to the This PC selection. I am not sure but I think searching This PC should search this PC
Help!

The screenshot shows the search hasn't finished running yet. Searching every drive will usually take some time, if not using indexed search.

(OTOH, if using Everything's indexed search instead, the results should come back almost instantly. If Everything is installed and configured to work with Opus, you can select it in the search field by clicking the magnifying glass.)
