Error with RASPA2 with 5185 atoms model

[sree.h]

Dear all,

I have been stuck with a problem for over a month and a half now, and I am still unable to reach the end of it.

I have defined pseudo atoms for 5185 atoms and force field mixing for 5185 atoms. I have the atom site label the same as the pseudo atoms, and the force field mixing and consistency in label are maintained. Yet I am getting this error!
This is my input file. If anyone is interested in resolving the error please ping into this thread. Thank you!
