Welcome to the horrible new world of windows 10 1903+ fellas! Common issues are windows has installed DCH so you now can not install any drivers, Solution is install without network cables and only install DCH drivers you can NOT now go from DCH to standard drivers.
Another is great but i have no working control panel, Thanks to DCH which we never wanted or needee you may have to visit Microsoft store and install the Nvidia control panel from there, Yep thats right you just downloaded the driver but now need to visit the store!
Microsoft caused a lot of trouble, Headaches and hassle recently with undocumented changes the above is but the tip of the iceberg. If this is all that bothers you about the latest windows 10 be thankful!
