For anyone else who tried the FrostyFix and Frosty Mod Manager route, it didn't work for me. Which seemed silly on the face of it because I don't and have never had any mods installed for EA. I was poking around the Battlefield 1 install folder (C:\Program Files\EA Games\Battlefield 1\) and on a whim decided to check out EA Anti Cheat, since I believe it is new to the game. I opened up the EAAntiCheat.Installer.Tool, updated it, and then repaired it.
And wouldn't you know, FINALLY, the game will launch. Hopefully this helps others.
Ty :-)
