Why does increasing dt result in an error?

[YXY101676]

Dear MOOSE users,
I am using Moose to calculate crystal plasticity, but the required deformation is large, so in order to speed up the calculation, I tried to dt, but the following error occurred:

Is there any way to accelerate the computation?
Best Regards,

Hello

You could work on improving the preconditioning, or making the mesh / problem smaller.
Large dt is not always safe in problems with deformation.

for explaining the error I ll need a backtrace. Use these instructions to generate that if it's not already displayed
