Sounds like an anticheat issue and you may or may not be completely at the mercy of the developers. Titanfall 2 does use EAC though, and Steam does have a Proton runtime for it (should already be in your library but might not be installed). Again, not a guarantee this will solve your issue because anticheat software does not play will with Linux for numerous reasons.
