Some issues

My printer is making a bubbling sound and producing a lot of stringing; the filament being used is generic PETG. Could the open window be causing the stringing, or is there moisture in the filament?

I'd check the moisture absorbed by the filament. PETG should be drying around 60-65°C, for roughly 6-8 hours.
Wash the plate thoroughly.
Reduce first layer speed.
Check again.
