I try opening Eddie on my fairly new Windows 11 computer and it flashes up briefly before disappearing.
It was working perfectly for several months and then this happened.
When I tried to shut down, Windows said Eddie was preventing shutdown.
I forced it to stop with Task Manager.
When I restarted it asked if I wanted Eddie to make changes to my computer. I, maybe foolishly, said yes.
I uninstalled Eddie and still got a message that it was preventing shutdown.
I reinstalled it, hoping an update may have fixed the problem, but it's the same.
Edit: I have now solved the problem. I had to manually reopen the main interface and was looking in the wrong place for the icon.
