I'm experiencing the same issue. Since the latest update, I've played over 10 Rivals matches, and in 2 of them I couldn't control my players at all. I reported both players through the EA app.
In the most recent match, I was unable to make any changes to my squad no substitutions, no tactical adjustments. The game has become incredibly unstable after the update.
On top of that, defensive gameplay feels completely broken it's like an open highway. (Granted, maybe I'm just not very good, but even in pro level matches we're seeing over 10 goals per game, which says something.)
