Multiple Pumps on Hayward OmniLogic System Keep Shutting Off

I’ll try to be brief but thorough. Problems started when my main pool pump would shut off intermittently. Then, it would immediately trip the breaker. So, I knew it was shorted windings/bad motor. I bought a new motor and installed it. It would turn on for a few minutes, and then turn off. If I turned it off in the Hayward app, and then immediately back on, it would run for another few minutes. I thought maybe I had a bad capacitor, so changed that. No luck. Then, I thought it was bad motor, so I switched it with another. Same thing happened.

While this was happening, my flow sensor went bad. I ordered a new one, but temporarily put a shorted phone wire in there to clear the code. Code is clear now, but now my motor only stays on for a few seconds (never several minutes).

I thought this was odd, so I turned on my waterfall motor. It started doing the same thing! Would stay on for a few seconds, and then turn off. If I turned the valves to do half waterfall and half bubbler, the same motor would stay on BUT it seems to turn off/on every few seconds (like it loses power temporarily for a fraction of a second).

Something is making a creaking noise near my skimmer when motor is on now (I think it’s a new sound). Do I have a blockage that is limiting flow perhaps?

Is my control board bad? I’m at a loss!
Edit: Receiving a MSP_DEV_COMM_LOSS,Comm Loss Device:00-46-03-73-62 HUA:MSP error too.

Edit 2: I checked main pool pump voltage between L1/L2. It goes from 240 to 0 when turning off, so that indicates control board issue?
On water features motor, when it is waterfall/bubbler tougher it drops for split second to 240 down to 230 every few seconds but motor stays on. On waterfall only mode, it drops from 240 to 100 and then motor turns off (I assume because it is undervoltage).
Control board issue?

Follow up for those who search. I decided to switch the relay wires to see if I could get another motor to work. It did! So, I changed the programming to point to new relay, and then changed it back. I wonder if the firmware update screwed something up.
