I, too, have this problem. It started late last year when Whatsapp was updated. You can temporarily fix it by going to Settings - Apps - Whatsapp - Advanced Options and Reset (Repair does not work). However, next time you re-boot the "Windows cannot access...." will be back. I have tried everything mentioned and in addition I have tried
"Taking ownership" of the two 5319275A files
Deleting every reference to Whatsapp in Registry Editor
Whitelisting the two 5319275A files in Malwarebytes
It's nice to know I am not the only one.
