Layers lifting (not first layer) on random parts  

Layers lifting (not first layer) on random parts

My printer seems to be temperamental. I have printed two perfect prints of the desk organizer  and suddenly I can't print it anymore. Had first layer issues but I washed the bed and things stick. Glue doesn't help since it's not a first layer issue. Here's what I tried thus far:

• Different bed sheets
• First layer calibration
• Swapping filaments (Overture PLA, Polymaker PLA+)
• Drying filament
• Higher extruder temperature (180 to 220)
• Higher bed temperature (60 to 85)
• Slower speeds (down to 50%)
• Larger or smaller layers (2mm to 4mm)
• Z axis lower or higher

I printed other things and they all print perfectly with the same settings on my Mk3+. As long as the print is not a very large flat surface, everything prints well. I calibrated the bed and nothing changed.

Here are some photos

Lifted on fifth layer First layer looks great First layer works It happens in multiple places, and not always on the same place lifted off after third layer Smooth first layer

At this point I am not sure what the next step would be. Any recommendations on what I can do? Very odd since it printed the same exact gcode file twice, and then this started happening. Note that I swapped the filament after those two good prints and the filament was inserted and wouldn't come out, but the extruder was not extruding any filament. So I unloaded it again, loaded it, and everything got back to normal. Well, not everything since I can't print this anymore.

Appreciate the help!
