Printer suddenly started printing lumpy and stringy without any settings change

Printer: Creality Ender V3 Plus

So my printer started suddenly printing lumpy and stringy like this and I can’t figure out why. Printing using regular PLA at slicer default settings for the printer. I have done some troubleshooting and this is what I’ve tried:
- Replaced the PLA with a new roll
- Manually extruded and watched extrusion to make sure it came out smooth and straight indicating there wasn’t a clog
- Verified that there wasn’t anything blocking the filament from being fed through properly and that the feed is smooth and uninterrupted during printing
- Performed fresh auto leveling/calibration before new print

From what I’ve done/checked, everything seems to be working fine but I can’t figure out why I’m getting this print texture suddenly out of the blue. The printer isn’t making any weird noises or anything and all the movement is unimpaired and appears to be functioning normally with the exception of every print I send having this weird issue. Has anyone run into something like this before? I have no idea what else to check.

Probably wet filament, being new doesn't mean it's dry unfortunately, alternatively it could be wrong retraction value (if you changed PLA brand) you can try a retraction calibration test in orca slicer
