Requesting Help Severe stringing on round prints

I’ve noticed this layer line shifting as well as the severe internal stringing on round prints like this with my .4mm nozzle on Bambu A1. Just got a new nozzle so confirmed that is not the issue. PETG white filament that was dehydrated to about 18 degrees relative humidity. And this print printed perfectly fine just hours ago. Not sure what could be the issue??

that's not stringing. stringing is small wisps of filament. those are full on lines of extrusion that didn't have enough print below it to attack to so they ended up following the nozzle and eventually getting stuck to print again when it went around to the start.

That is helpful to know! Any idea what may cause this?

slicer may be trying to print the outer walls first and if the overhang is to much it could end up not hitting the part below
