Musescore 3.5.2 won't load

Guys, I am a musician not a coder or programmer...
I love musescore!,.....and I always load the latest version you send out. Up till now they loaded fine.
But this 3.5.2 seemed to load ok.... but now when I try to get it to come up... it gets the initial Musescore screen up, asks me if I want to restore my old session... I answer YES ... it starts to load and disappears....
I answer NO... it starts to load..... and disappears....
I am on a Dell Inspiron computer... with Windows 10...
Never had a problem before... but this one...just won't load...and work.
Suggestions?
