python module stuck in loop with some pdb files

[ydzdfci]

Describe the bug
stuck in infinity loop with some pdb file

To Reproduce
File: 7szu.pdb1
According to the exmple provided,
my_mol=PDBComplex()
my_mol.load_pdb('7szu.pdb1')
my_mol.analyze()
The program will stay in this step when running.
I tried to use timeout decorator to exit the function calling, but it did not work.
I'm wondering that if there is anyway plip module can work like website that will exit after a preset time and send back exit code.
Thanks
