Sensorless homing - Endstops always triggered

Hi I am currently unable to get sensorless homing to work... V-core 3.1 400, RatOS 2.0; Octopus 1.1, TMC 2209

I have enabled [include sensorless-homing-tmc2209.cfg] in printer.cfg and copied the include sensorless-homing-tmc2209.cfg into the directory where printer.cfg is (image3).
My X and Y endstops are responding as triggered.
negating from endstop_pin: tmc2209_stepper_x:virtual_endstop to endstop_pin: !tmc2209_stepper_x:virtual_endstop does not work, klipper calls error (image2).
I did not try to swap drivers but I checked during assembly and did not see any damage. I doubt both X/Y drivers would be faulty? (edit: the motors themselves are behaving fine)

I feel like there's something rudimentary I did not check or do not know but I've already spent more than two hours on this
