Capcom broke the game after the update, if you bought the winter expansion you just can't play it because it crashes. for now it can only be played if you have not bought the expansion (I was able to verify it by trying both versions)
My guess is all the intrusive anticheats is causing problems.
I know there is no ETA on an update for the trainer for the full game, but will there be a trainer for the new demo?
seems... unlikely
best,
