From the log:

TMC 'stepper_x' reports GSTAT:      0000001d reset=1(Reset) uv_cp=1(Undervoltage!) register_reset=1 vm_uvlo=1
TMC 'stepper_y' reports GSTAT:      0000001d reset=1(Reset) uv_cp=1(Undervoltage!) register_reset=1 vm_uvlo=1

This is a problem:
uv_cp=1(Undervoltage!)

Unable to write tmc spi 'stepper_x' register DRV_CONF

You want to configure SPI until DUMP_TMC STEPPER=stepper_x start to report some meaningful information.
In your case, with 2240, the actual temperature.

JFYI :

It is okay on the cold start: Steeper drivers getting too hot - #17 by nefelim4ag

Try switching to software SPI instead of hardware SPI.
