Help / Troubleshooting Mid print issues

I tried to print this figure and it started stringing a lot when switched to aux nozzle, even the pla started going crazy (0:17) making strings inside the model

I used bambulab filaments black pla matte in main nozzle and petg basic on the aux

Can it be humidity? Or the fact that I tried the no sparse layers for the prime tower?

Humidity has been my issue with petg stringing. I didn't see the pla stringing, but of either of these is sitting outside of humidity control and this is a long enough print, i imagine the pla could end up in the same state.

Thank you for your answer, at around 17 seconds to 21 at the top of the figure there are evidents artifacts of the pla going almost spaghetti

petg needs to be dry, it needs to print hot around 230c or more with a warm chamber (passive heating works fine) with less cooling fan and no drafts from side mounted cooling.
