Built-in keyboard and trackpad suddenly stopped working, cursor stuck in top left corner.

I have a late 2017 13" MBP. Today the trackpad and the keyboard stopped working at the same time. The only thing that works is the power button (and the touchbar). Nothing happened prior to the incident so I don't know why the hell they stopped working all of a sudden. But I've noticed one thing. The built-in keyboard and trackpad DO work on the log in screen. When I restart the computer, I can introduce my password with the built-in keyboard, move the cursor around with the trackpad and click log in just fine. I guess this means it's not a hardware issue (or at least I hope so). However, when the desktop appears, the cursor gets stuck on the top left corner and the keyboard doesn't work either. I've tried doing SMC and NVRAM reset and haven't had any luck. Rebooting in safe mode doesn't work either. Right now I'm using an external bluetooth keyboard and mouse.

I've thought about doing a factory reset to the computer but would that fix anything?

Any ideas?

Thanks!

When you say rebooting in safe mode doesn't work, do you mean it won't boot in safe mode, or that safe mode doesn't fix the problem?

It does seem like a software issue like you say, since it operates early in the boot process but not later. A factory reset might help then.

Just had this problem and fixed it. I think it has to do with your system files not loading properly

Mine is doing the same thing. Did you get a fix for this?

It fixed itself I guess. Everything I tried didn't fix it so I kinda gave up. A few days later I started the computer and everything was back to normal and working fine again. I have no idea what could have happened. It hasn't happened again since then.
