Signal (7): Bus error

hi guys, I hope you are all are still alive and healthy after this terrible ordeal with covid-19 thingy.

I have a question regarding data save using JLD2 package. Please see following the error that I get sometime during the run of my code (this means not immediately at the beginning) and for more I am saving simple Float64 Array of Arrays maximally.:
