frictional contact - convergence problem

[zizou3]

Hi, I am writing to you to ask for help.
I have a problem with the contact "Frictional". I'll show you screenshots of my settings and program the console errors. Everything will be shown in the screenshots. The problem is that between the beams and the top element and the bottom element is Frictional which causes a lack of convergence. I do not know how to deal with all of this, especially since this is a problem in my thesis. I need to find out what are the internal forces in the joints of these elements.

Model presents powered support, and support beams represent an extreme variant of contact with rocks.

here are screens:
