[Wien] Error in dstart phase

Dear users,
I am running Wien under fortran compiler. The purpose of my calculations is to have the vibration modes of PbBr4 (1D chain).To do so, I generated, using the Phonopy program, 30 supercells starting from the PbBr4.struct. The problem is that I did not achieve the initialization. After running init_lapw from a terminal on one of these supercells (001.struct; attached file), and choosing the default parameters (except for Rkmax=5), I obtained the following error (dstart phase):

I tried 2 others .struct files and I got the same error. The 001.struct seems to be right. So I really don't understand what is happening. It would be great if someone can help resolving this case.
Best,
Hamdi
