Hi!
First attempt to run setup.com /mode:uninstall gave an error message that "Windows SBS Console" was open.
Closed the console and tried a second time. New error message that "DataCollectroSvc" could not be running.
Closed that as well and tried a third time.
Now the uninstallation process starts and goes on until "Stopping Services" that fails with error message:

Perhaps the two first failed uninstall attempts is the cause of the last error?
In any case: How can I solve this?

Can you reboot the server and run the uninstall again?
That was (like so often) the solution.
I wasn't sure if it would break anything to do a reboot, so thank you for your advice!
Rebooting seems to have solevd the issue
