EA AntiCheat problems after update to 1.14

The game was working perfectly this morning (in v.1.13). After updating to 1.14 the game won't start with the splash screen showing problems with AntiCheat:

Never had this before, and nothing on my system has changed since this morning (except the update to 1.14.)

AntiCheat was already reinstalled multiple times after PC restarts, but without success.
