FC 26 Fails to Launch on PC – Black Screen after Anti-Cheat Splash Screen

Hello, try putting your PC offline then uninstall and reinstall EA Javelin anti cheat then connect to the internet again and check if it works, if it doesn't work you can try clearing the cache of the EA app, if it still doesn't work you can first make a backup of the EA SPORT 26 folder (located in C:\Users\your user\AppData\Local\EA SPORTS FC 26) then delete the original folder so as to force the game to recreate clean data from the last update.
