Word docs don't display in viewer pane

Up until now Ive had no issues, but today the Viewer Pane will no longer preview Word docx files. I just get the Word Folder Icon. Word doc files and pdf view okay. Ive tried everything and followed all the suggestions including plugins etc. Anybody anu ideas?

The Word viewer is part of Microsoft Office, not Opus.

Is it working in File Explorer's viewer pane, for the same files?

If not, try repairing the Word installation. That usually fixes things.

If it works in Explorer but not Opus, it could also come down to antivirus blocking access to the documents via one program but not the other, but issues with the Word viewer are usually fixed by repairing Word, so try that first.
