Error: Time-Dependent Solver...May have reached a singularity. Time: 494.299 s. Last time step is not converged.

My model runs successfully when I set the fracture energy (Gc) to 10 N/m. However, when I reduce it to 2.5 N/m or lower, I encounter the following error:

Time-Dependent Solver… may have reached a singularity. Time: 494.299 s. Last time step did not converge.

I have already tried refining the mesh, but the issue persists.

I would greatly appreciate your assistance and comments.
