Hi, I had problems like this on Windows from time to time
for no particular reason.
In all my cases, I went to the program folder and clicked on the exe file
in the particular programs folder, and it would open, then I just right clicked
the same exe and selected send to desktop as shortcut, or create shortcut
depending on version of Windows.
Nothing to loose by trying, also stop your anti virus in case it is involved in the problem,
don’t forget to start it again though.
