BTT SKR 1.4 Turbo, BTT TMC2209 Drivers, Sensorless Homing Issues

So have a new bigtreetech skr 1.4 turbo with bigtreetech tmc2209 stepper motors.

Trying to setup sensorless homing however my Y MIN Endstop always shows triggered which means it never tries to home Y.
X sensorless homing is working fine?

>>> M119
SENDING:M119
Reporting endstop status
x_min: open
y_min: TRIGGERED
z_min: open

Anyone got any ideas?

Tried both Stock Marlin 2.0.5.3 and Marlin 2.x Bugfix

Has anyone found a solution to this yet? The only thing I have been able to do, to get the Y-Axis to work, is to install DRV8825 driver instead of TMC2209. I followed the video from Chris' Basement on YouTube, almost to the letter. [www.youtube.com]
