This only started happening a month ago and thought my prints were bad because of moisture in my fillament so I bought a whole new roll and they are still bad please help if you know what is happening.

What printer?

What version of Cura?

What operating system?

Are you printing from the SD, USB, Octoprint?

With the benchy loaded in Cura use "File | Save Project" and post the 3mf file here.  Post that gcode file of the benchy as well.

windows 10

I'll need that gcode.  I'll try printing it on my Ender 3 Pro.

Did you use File/Save Project or did you use File/Export.  Both generate a 3mf but a project file has your settings with it and a 3mf model file is just the part.

and here is the gcode 

CE3PRO_3DBenchy (1).gcode

I'm printing the benchy now and it looks fine.  So the mess we see is your printer's fault since the gcode is fine.  It looks like you are over-extruding by a lot.  There is so much over-extrusion that it may be hiding other problems but you need to get that sorted out first.  Your printing temperature is fine at 200 and 60 for the bed.  Your retraction distance at 6.5 should be keeping down the stringing but your benchy has quite a bit.

 

I'd start by re-calibrating the E-steps but you need to look at the trolley wheels and belts as well.  Something (maybe more than one something) has gone out of adjustment and you need to get it back.

What mainboard are you running?  I changed mine to a 1.1.5 silent board but I didn't notice any difference in print quality when I made the switch.  3 weeks later it burned the E-driver chip and my extrusion was all over the place.  Creality finally sent a replacement board.

 

EDIT:  This is printed from the Gcode you posted, that uses your settings, and printed on my Ender 3 Pro.  It looks like a 3DBenchy.  I believe that your printer has gotten funky and needs some tuning.
