the mass matrix is zero

Hello
I am trying to simulate my design. In the first step, I tried Mode Analysis but unfortunately I faced this error:
The mass matrix is zero
Please let me know how can I fix it?
Of course I read last blogs which talk about this problem such as "poisson's ratio" parameter or mesh.
It didn't fix.
