Windows 10 App Crashed and Won't Restart

Hi @Nick-B,
Thanks for the suggestion. I did uninstall via “Add & Remove”, I deleted the /AppData/Roaming/Local folder, reinstalled and restarted prior to attempting to launch the app. When I was rebooted and attempted to launch the app I have the same issue.

I get a momentary spinny wheel cursor, then nothing. It never shows up in the Taskbar. It does then show up under “Background processes” in the Task Manager (3 instances), but not under “Apps”.

UPDATE: This did work! I must have deleted the wrong folder or /AppData/Roaming the first time as I went back through the steps and found it a second time.

Now how do I restore my old “Local Sites” folder which contained my old projects? I have dropped them back into their respective folders.
