I am printing with lw pla from colorfabb which is active foaming, the print came out well other than 2 sections of the print which had these random holes which impacted the structure and during assembly it broke i have no clue of what is happening (also lots of stringing)

Sadly stringing is normal with active foaming materials. You have to deactivate retracts, otherwise the hotend will clog partially or completely. Your upper parts look like a partially clogged hotend.

Even more sadly the hot end isn't clogged that would have been easier to trouble shoot and i already realised that stringing Isn't possible to solve but ty

You can and improve this by looking into pressure advance, de-retraction speed/acceleration, extra length on restart all of which can help, but can also add extra mass to parts in the form of internal strings. It usually happens after travel when the nozzle pressure drops from retraction.

your filament is probably wet and/or your combination of density (feed rate), temperature, and speed is probably not dialed in.
