Here’s an interesting article which details Thrawn’s flaws quite thoroughly. Among them are a tendency to make assumptions, plot out overly convoluted plots which can be foiled by even one thread being unraveled, etc. In other words, he often thinks to much. He even did this in Rebels . He’s not invincible.
