I had give Groupy another try last week, and installed it. But then noticed after some time, that certain GUI elements of Windows 10 were now broken and couldnt be opened anymore.
For example gpedit, or the network GUI window, when I click on them I get this message:
Trying to open gpedit:

It says something like "Cant open the device or path or the file. You maybe dont have the necessary rights, to access the element.".
Deactivating groupy and rebooting Windows 10, and it works again.
I am using latest version of Groupy and latest stable version of Windows 10 1909.
