“Class not registered” error after install of PowerToys in WIndows 11

After installing Microsoft’s PowerToys in Windows 11, at every boot, an error dialog box appears

Class not registered error dialog box

to warn me a class has not been registered.

Uninstalling PowerToys and reinstalling it does not solve the problem.

I see here similar problems have been solved with

{Start}{Run} https://regsvr32 NAMEOFDLL

but I don’t know which DLL or other executable should be specified for the Microsoft CommandPalette PowerToy.

How do I remove this error dialog box?
