Marlin [BUG] TMC2209 Sensorless Homing not working

Description

I installed TMC2209 from Fysetc on my SKR 1.3 of my CoreXY and tried to get sensorless homing to work. UART connection works fine, but X and Y endstops always show as "TRIGGERED". Jumpers on the SKR are closed any I ensured that there is an electrical connection between the DIAG pin and the endstop. I varied sensitivity from 0 to 250, but nothing changed.

Steps to Reproduce

Most recent Marlin 2.x bugfix G28 XY

Expected behavior: Axis home

Actual behavior: Axis don't move, X/Y endstops are triggered

Additional Information

That's a useful answer
Without any help

Hey, im having exactly the same issue except my endstops are now reading "open" on X/Y but the motor just stutters as if its sensitivity to sensorless homing is very low?

I have adjusted sensitivity from 0-255 and even taken the belt off my XY but the motor still just turns maybe 2/5mm before stopping on a home command?

this is very bizzare as i can read positive voltage from TMC2209 DIAG1 to Xmin signal pin?

running SKR 1.3 /TMC2209/ COREXY just as OP

heres my M122
