Have you tried adding L's and C's to ensure that any changes in current and voltage are continuous?

Unfortunately, I cannot change the problem element which is the snapback. However, your suggestion of adding a series L might be helpful.
In the meantime, I was able to add large resistors in || to the elements (around 1 MOhm) and achieve convergence, albeit still with a very slow simulation, and of course, it is not 100% clear whether the results are still sufficiently accurate.
I would have expected so since the added resistors are too large to permit any significant ESD current to flow through them, but the results seem a bit different.
