Marlin 2.1.2.1 ~Bltouch behaving wrong Ender5 build

I'm currently experiencing a weird error with the CRtouch for the ender 5 with the 4.2.7 motherboard. I've configured marlin 2.1.2.1 for it, built the firmware and flashed it, yet upon testing the BL touch doesn't activate and the bed doesn't move up (if the z limit switch is disconnected). If the limit switch is connected it moves up, ignores the CR touch (despite it being activated) and stops with the limit switch... does anyone have any ideas? (to test the CR touch seperately I loeaded this firmware: [forums.creality3dofficial.com] and there it works flawlessly, so I can rule out any hardware flaws) my config files are attached to this msg and a video describing the problem is available here:[drive.google.com]

If the bltouch/crtouch is in any way plugged into the z-min plug, the you use this

#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
//#define USE_PROBE_FOR_Z_HOMING

If it is fully plugged into the 5 pin probe port you use this

//#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
#define USE_PROBE_FOR_Z_HOMING
