Microprobe V2 no works with Octopus Pro V.0

I have attempted to install a MicroProbe V2 on my Octopus Pro V0 board running Marlin Bugfix 2.1.X, but I can't get it to work. I'm sharing a video of the issue to see if anyone can tell me why this is happening. I have already tried using pin combinations PB6 and PB7, PB6 and PC5, and PB6 and PG10, but it doesn't work in any configuration.

I have made a video showing the behavior after powering on. At second 27, it retracts, and without touching anything, at second 72, it extends again, stays out for 10 seconds, and then retracts again. This cycle continues indefinitely. If you try to home the printer, the sensor remains retracted, and if you try to extend it manually, it gives an error and prompts you to restart the printer.
