LT spice -Analysis failed

So I recently started using LT spice to help me with studying circuit analysis and it has been really great so far.except for this one circuit that is refusing to run for some reason. Every time I try to run it i get the error message: analysis failed: iteration limit reached.

here's the circuit I'm trying to run.

the problem seems to be connected to the current dependent current source (B1) because it runs just fine when i change the multi from *2 to *1 .
I have no idea why it's happening though. I would really appreciate your input on this matter and thanks in advance :3.

If the B1 multiplier is 1.75 some circuit voltages reach tens of megaVolts. I suspect (could be wrong) if the multiplier is 2 that some number limit of LTS is exceeded, so the impossible is being attempted.

Can you show the example you are working from?
