Why does my brain freeze when I try to switch binyanim mid-sentence?

I've been studying Hebrew grammar for months and I can identify the root letters easily, but when I'm actually speaking, my brain gets caught in a loop trying to figure out if I should be using Pa'al or Piel for a specific verb. It’s like a mental block that makes me sound like I'm reading a textbook instead of having a conversation. Does anyone have a mental hack for visualizing the binyanim patterns in real-time, or is this just something that only clicks after years of practice?
