So the matrix being singular shouldn't be the issue since my matrix assembly routines are independent of the petsc/slepc installation I use. Also, diagonalization happens for smaller matrices.

Use -eps_view_pre (it should view settings at the beginning of solve), or run a smaller case (settings should be the same).

I will also need the other matrix, otherwise I cannot run EPS.

Also, tell me which version are you using now, and which version worked before.
