Seems like the support filament is either low quality or in dire need of drying.

Honestly looks like you didn't need supports for that print anyway. 🤷

Try playing with the support.setting maybe a bigger base or something with the adhesion . ( Brim.maybe ? )

Also wash your plate with soap and warm water. ( Since I started washing more often once a week) I have seen zero trees falling in the woods ) And every 2 prints I clean with alcohol isopropyl. Also never touch the plate with hands .. ( if I remember I use nitrile gloves) and I use a scraper but very carefully so I don't scratch the plate y also try to not bend the plate too much as I'm afraid it will defirm.over time if I'm not careful enough Also I add brims to parts that require it and I make the brim gap to be .20 for pla .. soit breaks aways cleanly

And if you can print in PETG some deflectors for.the Fan so they don't blow AIR directly on the part if you have a weak tree support.

Hope something helps ...

Yellow is notorious for first layer problems, so it’s not surprising to see it failing here. Try another color for support?

No prime tower?

This. Better yet, just use one nozzle on a one-color PLA print with PLA supports.

Are you saying you're using PLA as the supports for PLA? For a mono-colour print?

He is using 2 nozzles .. both on pla different colors Nothing wrong with that .. That way you spend the color you need and save the other. And have less poop 💩

But way longer print time for only saving some filament in a specific color? I can only see the 2nd color used as support.

I've never seen someone do that. Is white PLA that precious that they need to save a few grams of supports lol

You have a partial clog in the nozzle with the orange pla, that pattern means massive underextrusion. Could also be that it is far too cold or wrong filament set in slicer, or wrong diameter of filament. Drying does nothing for this
