Musescore doesn´t open

hi,
I didn´t jchange anything in the program. I only finished a score and the closed the program.
But then after trying to open the program, it doesn´t open anymore.

On the button of my screen i can see the symbol of the program, but on the screen the program doesn´t open.

I tried different versions of the program and different scores.

Can me help someone?

Thanks for you help!

kind regards
rubito
