System crash while opening Musescore3

Hello,
since today I have the following problem using Musescore: I can't open Musescore any longer (I've already reinstalled Musescore). Clicking on the Musescore icon the whole system crahses and I have a bluescreen. I'm using windows10 64bit and the latest version of Musescore. I've already searched for solutions in the forum, but all the proposed solutions don't work out.
Is there anybody with similar problems?
Kind regards Debo
