EA app not launching

When I try and start up battle front the ea app will pull up to sign in and then 5 seconds later will close automatically. It has been consistently doing this for 3 days in a row I’m just trying to play battlefront 2. I recently tried out the kyber Star Wars expanded thinking that it was totally fine from what I read it was totally fine to do. After I installed it I could not play just my regular battlefront anymore. I then uninstalled all of everything I had from kyber in my pc. But still I can’t get into my regular battlefront. 2 days ago it actually aloud me to play battlefront It then crashed and I was no longer allowed to play it again. It seems to be the EA app above all battlefront 2 seems fine I just can’t even open my EA app. I’ve tried everything from every video I have watched and still nothing seems to work.
