[Wannier] pw2wannier90.x: something wrong

[Zeina Al-Dolami]

 Dear Wannier90's owners and develpoers,
I am running pw2wannier90.x to generate seedname.amn, seedname.mmn, and
seedname.unk. However, I get the below error message. I am not sure about
the reasons. Would you please help me with this problem? Any feedback is
greatly appreciated as I am new to this field. Thanks in advance
