Icon on the taskbar

The Opus icon that's shown on the taskbar keeps changing all the time depending on which folder on which disk I open. For example several of my (external) disks have their own .ico and that shows as the Opus icon.

This behaviour started very recently (perhaps after a Windows Update).
Is it possible to get the trusted standard Opus icon permanently back?

BTW Opus is not pinned to the taskbar


A new Opus setting....

Thank you for the fast reply.
