Apex won't launch

I am trying to launch Apex from the EA app on PC. I have a ton of skins and things in this account, so I would like to be able to access it. I haven't actively played in a few years, so this is my first attempt in years to try to start the game. It's also following a fresh install of the EA app, Windows, AND Apex.

I've tried reinstalling, restarting my computer, deleting files that random people across the internet have recommended deleting, repairing the game, running it while all firewalls and antivirus are temporarily turned off--literally everything I could think of and find online. Every file and folder related to EasyAntiCheat and Apex are exclusions for my firewall while it's up too, though since it didn't work with everything turned off, I'm guessing it has nothing to do with that.

When I try to launch the game, I see the "SplashScreen" image (the one in the EA Games/Apex/EasyAntiCheat folder) and it loads all the way up to 100%. And then it goes away and the EA app unminimizes itself/pops up again. No crash information, no code, nothing. 

When I try to open EasyAntiCheat_EOS (some people online recommend changing a setting in it) I see a window flash on screen really really fast but then it's instantly gone. I don't know if that has anything to do with anything, but I want to provide as much info as possible.

Any help appreciated. 

I can see other people having this problem across the internet and this forum but most of them seem to never get any solutions and I've tried every suggested solution I've seen, even if it didn't work for them. And none have worked for me either.
