A strange case of missing Destop toolbar in the Taskbar

Greetings.
After installing the latest update on one of my machines, the Desktop toolbar was found missing from the Taskbar. Adding it again doesn't seem to work as it would disappear upon rebooting. The other machines were fine. Appreciate any kind assistance to resolve this strange issue.
Many thanks and best regards,

It's titled "A strange case" because only one out of four machines developed this issue.

Just thinking outside the box here:
If you unlock the taskbar, add the Desktop toolbar, then lock the taskbar again, then restart does it save the Desktop toolbar?

If that doesn't work, if you go to Toolbars, New Toolbar, then select your Desktop folder, it will create an additional entry called Desktop. Does that persist across reboots?

Thanks for the kind reply, cknoettg.
Both of your suggestions did not work. However, removing and enabling the language bar seems to have solved the problem for now.

Your wicked sense of humour is certainly most intoxicating, although I suspect it may not be intentional.

That's the spirit.
