[PC] PvZ BFN Not Launching

I'm having some troubles with my Pvz Bfn for a couple of days now. Firstly for some context i this all happened after i downloaded fallout 4. After a couple of days playing fallout i went on bfn and it was working perfectly but the screen wouldn't full screen and the visual didnt load. But the game was running in the background because I heard the music and me selecting things. After that I looked online for some answers and nothing worked. So i deleted the game and redownloaded it today to try again and the game wont even launch. 

I already tried fixing the picnic but didn't work. I wanted to repair the game on the EA app but there's no option to do so. 

For a note Pvz Bfn worked fine before I downloaded fallout.
