MINI+ just won't stop stringing and oozing

(Not sure if this is the right forum since it's not "first prints" troubleshooting)

I got my MINI+ about a month ago and it printed brilliantly until about a week ago. Now, it's stringing like crazy even with PLA.

I have tried pretty much every fix out there:

-dried the filament

-reduced print temperature (even though it was fine before)

-cleaned the nozzle with a needle

-multiple cold pulls

-adjusted extruder idler tension

-disassembled and cleaned the extruder

-replaced the nozzle

-replaced the hotend PTFE tube

-disassembled the hotend,making sure it's as far up as it will go and that the PTFE tube is long enough

And yet it is still stringing like absolutely crazy (see below) and it's also oozing a lot more than it used to in the beginning. Does anyone have a clue what on earth might be wrong with my printer? Did something fail after a feew weeks and I haven't realized?

Did you increase your retraction?  What is it set to and which brand of filament are you using?

Retraction is at the standard for the current PrusaSlicer and I'm using Sunlu PLA (pictured above) and Prusament PLA (not stringing as badly, but still more than it used to)

Same problem!!!

I just got a mini and it's doing the same damn thing! Two weeks of 17+ hours a day trying to get this junk to work! Did you ever find a solution!??

stringing

I have had several rolls of filament string a lot.  I had to dry the rolls to prevent it.  Consider trying another roll.  Chat on the eShop may help also.
