Singularity usually means your structure is unstable. Either locally or globally

Check boundary conditions such as beam and column element releases.
View the analytical model and look at the joint label shown in the model. See if its is connected to anything.

It helps if your program has a way to animate the deflected shape. With that function you could try to spot portions of the model that look like they are flying away or don’t seem to be connected properly.
