Nonlinear solver did not converge in CFD module

I am performing a study where a rectangular body is rotated at a constant frequency through magnetic torques that are decomposed into force vectors. The forces act on a corner of the elastic object and cause it to propel itself in a corkscrew motion.
The object does not have the motion that is expected and fails to solve due to a convergence error. Point probe graphs for velocity and displacement show gaps and give NaN in the probe table.
I suspect this is due to a singularity error or a solver issue, but I am unsure how to resolve it to fix this issue. The file is attached in this post.
