Windows 11 File Explorer Preview Pane for PDF files

[pjw001]

I am running Windows 11 version 21H2 patched up to date and have noticed this problem recently, although I am not sure exactly when in relation to recent patches.
When I open a folder the preview pane shows "Select a file to preview".
Selecting a .jpg file shows the preview.
Selecting a .doc file shows "No preview available" - expected as I do not have Microsoft Office.
Selecting a .pdf file causes the preview pane to go blank.
Untick the Show Preview Pane option, close explorer, open explorer, tick the Show Preview Pane option.
Selecting a .pdf file now shows the preview. (This does not work without closing explorer and reopening it.)
Has anyone else experienced this, and more to the point, does anyone know of a fix?

Thanks.

This seems to have fixed itself. I would guess that one of the Microsoft updates silently repaired the problem.

And the problem is back again.
