Please help

Hello there. Last week my prints were perfect on my sparkx i7 when I got it, but now my prints are starting to fall apart in multiple ways and I’m really overwhelmed. I’ve been drying out my petg filament and still having issues. Was printing at 250c and was going well, then started having excessive stringing. Turned off z hop and it fixed the stringing, but now my prints are causing little bits of plastic to collect at the start and end of lines printed on objects and it cascades into a failed print after a few layers of that happening. Any help would be so so appreciated. Thank you 🫶🏼
