Prusa I3 Mk2s Z motors always on

[Level3301]

The problem

Raspberry Pi 4 running AArch64 (Archlinux for Arm based computers), OctoPrint runs as a separate web application on the Pi.
The Pi is connected via usb to the Prusa i3 mk2s printer running latest firmware.

I am worried about Z axis motor failure. It seems that the motors are always powered, since they're warm on touch. Other motors aren't.

I tried sending M84, M18 codes manually but it seems to have no effect. (GCode for powering off the PSU does nothing.)

I did not have this problem before using OctoPrint.

Help is appreciated.

Thank you

Did the issue persist even in safe mode?

If you could not test in safe mode, please state why ("currently printing" is NOT an excuse!)
