Working with a non-converged stationary solution

I'm simulating a time-dependent nonlinear electromagnetics problem, where I use a stationary solution as my intial value. Since I updated to COMSOL 5.6, the stationary problem no longer converges. I used to have the relative tolerance at 1e-12, and have tried several different values of the relative tolerance, without the stationary solution converging. (I've also tried some different settings as well but summarizing all of those would be a minor essay.)
I can see on the convergence plot that COMSOL always finds a solutions which is almost reaching the convergence criterias, for all relative tolerances I've tried that are <1e-10, see attached file. Is there someway I can retrieve that almost-finished solution and use as initial value in my time-dependent simulation?
Other ideas on why the stationary solver is not converging is also welcome.
