Try using semiimplicit apdl command in the second step see what happens (see help manual for that).

So entre a command snippet with that command and activate it only in step two (in the command snippet there is a step selection under settings)
(see here for details on step selection:

For ref., the semiimplicit method switches to an Explicit formulation if we do not get convergence).
All the best
