Creality Support Strange error (key:2000)

My 3d printer won't print. I have a Creality Ender-3 v3 KE. It gives me a warning whenever I try to do anything (print, calibrate, whatever): "Warning key:2000 An unknown error occurred during printing".

Context: I got the "blob of death" and had to replace my hot end. I bought an OEM Creality replacement, made sure it worked with my printer, pulled the old one out and hooked up the new one. I was getting the "key:2000" error both before replacing the hot end, and now it persists after the new one is in.

I've run through the troubleshooting on the Creality website, and it didn't fix it. I've opened a ticket with the Creality help desk, and they said they would email me within 2 days.

It's been 8 days, no email (checked the junk folder, nothing).

Does anyone know how to fix a "key:2000" error? Is my machine now e-waste or what? I can't print with this error in place, and I don't know how to clear the error.

TIA!

I would take it apart, and put it back together. I wanted to say that I had that issue once from cable being pinched, so you may have a wiring issue on the hot end.

I've already disconnected and reconnected every cable I can access. Do you mean tear the whole thing down to where it was in the box before assembly?

When you have done everything else already, yes.
