How to deal with this problem.

We (the VASP Team) don't provide support for vaspsol.
Some other users of the forum might be able to help you.
Alternatively, you might ask this question in the issues in the vaspsol github page:

well, you could modified src/mpi.F file to solve this question.
First, open src/mpi.F by "vim src/mpi.F" and found the "SUBROUTINE M_sum_s" at about line 1895, and then remove all the "!!" of this subfunction. Finally, compiling VASP and it will work fine.
GOOD LUCK!
