Issue in LAYOUT - Cover Grid Book Covers are missing

Hi,

I have Calibre Portable Version Installed in WINDOWS & due to last month update, by mistake my Antivirus Kaspersky was ON, due to which after the update, when Calibre Portable Restarted, my Book Covers got DISAPPEARED in LAYOUT - COVER GRID View?

Book covers are available in Calibre Library in Induvial Books folder, but not showing in Calibre COVER GRID View. Latest Version of Calbre got Updated today, but still issue exist.

Please help to get this issue resolved, screenshot attached below for reference.
