I have a FYSET F6 board and support said "The sensor less homing is not supported these days , it still need more work on firmware." I said on your version they said "As i know , Marlin doesn't support that well too" is this correct?
The problem is X Bangs on side and does not stop only with error... Wiring all looks correct and pins look correct.
If go to Marlin 2.0 the display will not work as FYSET as not made a release yet... Guess could try with out display...
