I’m hoping you guys can help me figure this out. I have an ender 3 pro, running on marlin firmware.
Every time I try to print something one of the corners will lift up like that and ruin the entire print. I installed a crtouch to help with leveling, installed upgraded metal bed wheels to help it not fall out of level. Even tried a glass bed with glue and it still does the same thing. I used a filament dryer and have a heat enclosure.
I’m starting to run out of ideas on how to fix this. Any suggestions? The pic is how it starts and that was just a brim since I used to always use a raft and thought I should try that instead.

If PETg (which is where I've most commonly had warping), make sure Filament is very well dried. Try both raising or lowering bed temps and bigger brim.
Also, for funsies, try rotating print orientation 45 degrees if you can. Might shift stress away from corners to sides.
I might also try changing how the print sits on the bed to make it print more like a diamond instead of a square shape, since it’s always one of the back corners that start the lifting. Not actually sure it that would help but who knows
If it's always in the same orientation, it also can be caused by cold wind. Look at your enclosure ventilation, or try putting an obstacle there if there isn't an enclosure.
Exactly, that's what I meant
