[Cura 4.7.1 hangs when starting up and takes about an hour to start. Everything is slow with 0% CPU usage]

I am not sure if this is related.  this sounds like how my Cura 4.7 ran yesterday after the Microsoft update.  Then I downloaded 4.8 and installed and I still had the same problem.  I had a similar problem this summer with Autodesk Fusion 360 hanging and was able to fix by starting task manager and killing any process related to Nahimic.  Then I ran Cura and it popped right up.  I am using 3 monitors on a system that used to have a video card that used nahimic services and they are harder to get rid of than any addiction.  I can't find anything that I need Nahimic services for.  

[Can't Run Cura 2.4.0]

I believe that I have found the root to my problem. Maybe this will help you. I have a universal memory card bay in my computer that accepts 5 different sized cards. It maps them as D, E, I, L, and M. D and E are for sizes that I never use. So, these are always empty. I did the right click start and went into disk management and disabled the drivers for D and E. Now it starts just fine. I would like to see a configuration entry to just tell it where it should look though. It took me a long time to figure out. In my head, I don't think of D and E as being there because I don't have memory cards installed there. So, I was thinking that I don't have a D. But, my computer thought that it did.
