Cannot Preview Network Files Within File Explorer

Ever since the new Windows 25H2 Update, users cannot preview any network files as File Explorer states, "The file you are attempting to preview could harm your computer. If you trust the file and the source you received it from, open it to view its contents". I have verified "show preview handlers in preview pane" was enabled within File Explorer, and I enabled PDF Thumbnail Previews within Adobe Acrobat. This seems to be an on-going and consistent issue with other users according to similar forum posts. Microsoft, PLEASE fix!
