maybe there is something wrong in your path, but this cannot be seen if you do not provide also
the input file of the non self-consistent calculation (calculation=‘bands’ or calculation=‘nscf’).

However, possible coordinates of K are: (1/3,1/3,0), (2/3,-1/3,0), (1/3, -2/3,0), (-1/3,-1/3,0), (-2/3,1/3,0), (-1/3,2/3,0).
So, it seems that for sure the coordinates of your K point are wrong. Moreover, the coordinates of the M point (that you do not provide)
should be wrong as well, because it seems that also the band structure along M-Gamma has some issues.

If you choose (2/3,-1/3,0), use (1/2,0,0) for M point.
