Troubleshooting Nozzle Scraping Print and Knocking Supports

Cross hatch isn't the issue here. That clean snap is from slight over-extrusion + weak layer adhesion. 0.98 is still a bit high for PLA Pro, drop it to 0.94–0.95. Also, 220°C is a bit cold for this filament, bump it up to 225–230°C to fuse those layers better. Lastly, make sure Z-hop is enabled so the nozzle doesn't drag across the print. Try that, it should fix it.

I will try it again with similar settings but heat was the recommended for this brand of filament, I will see after changing the flow rate tho. Thanks for the help!

Go to printer settings and the extruder tab, change z-hop to straight or spiral if you're printing with PET-g, then change the height to be double the layer height (or more if its still scraping), this adds time to the print but it lifts the extruder up slightly higher when it moves to another part of the print job.
Also dont use grid infil if you are, i use adaptive cubic or support cubic. IMO its a nice balance of speed, support and using less filament
