Mass Effect Legendary Edition: An Incompatible Version Is Installed

For the past few days, I have been trying to play Mass Effect Legendary Edition through Steam. Every time I try to launch the game, the EA App opens and gives me the error message "Couldn't launch Mass Effect Legendary Edition. An incompatible version of this game is installed on your device. Uninstall the Steam version to launch."

If I don't try to launch the game through Steam, and pull up my library in the EA App, the game is greyed out and says to uninstall the EA version of the game. I have no idea what to do here. I've already uninstalled the Steam version twice, and I can't find any EA version of the game on my device to uninstall. I even deleted all of my save data for the game and that did nothing. I've uninstalled the EA App several times as well (a solution that worked when I was having problems with Dragon Age: Inquisition).

This is frankly infuriating. Why would I ever buy another EA product if I have to go on a days long quest every time I want to play one of their games?

Any help or advice would be greatly appreciated.
