Bug in empty pot

My empty pot was on the fire for a few seconds when I noticed that a live bug (smaller than an ant) was crawling in it. I quickly switched off the fire and removed the bug with a soaked tissue. I’m not sure if the pot had reached the temperature of yad soledet bo (some parts were hotter than others). Is my pot still kosher?

I had not thought any further about it in the moment, and used the pot for soup after that. But I’m now wondering if the kli rishon status + fire + non kosher bug + liquid from the tissue would have affected the kosher status of the pot.

Thank you so much!

Pot is ok
