I have been using Groupy since December of 2018 through multiple Windows 10 OS upgrades without any issues. I am currently running Windows 10 Pro 19045.2075.
Your issues could be a corrupted installation of Groupy or a compatibility issue with another app you are running. As a first step, I would also suggest a purge and re-install as basj suggests. Important! Run the purge and then reboot your computer; install Groupy from a fresh download from your account; and this is really important, reboot again.
