Sorry to hear you are having issues.
Reboot and load of computer taking extended time, and I see in the startup tab of file explorer on WIN10 Enterprise, what appears to be duplicate entries for Fences settings.
Windows 10 delay Application Startup by default, you can disable that and see if it help. https://www.howtogeek.com/403162/how-to-disable-the-windows-10-startup-delay/
And, from what I know, Fences needed to load twice for it to work.
I have a ton of Icons on desktop hidden in fences, divided into 5 categories, and was hesitant to uninstall and reinstall this Pro version, as I dont want to go through re-organizing back into the 5 fences again. (roll up style).
Purge and reinstall should not remove your saved layout snapshot : https://forums.stardock.com/486084/fences-support-faq#reinstalling,just make sure to redownload the latest version from your account, purge using the guide linked above. reboot after the purge, reinstall and reboot again.
To be sure, you can use this guide to save you layout snapshot https://forums.stardock.com/486084/fences-support-faq#backupsnapshots.
