If you look at the edge above the lifted corner, isn’t that supposed to be straight, or are the walls not meant to be flat?

My guess is that you need to print slower and/or increase nozzle temp. If the filament isn’t properly melted that also leaves tension in the material, which can cause corners to be pulled off the bed. I.e. cooling issues is not the only thing that can cause warping. What are your current slicer settings? I assume your high-flow nozzle isn’t PTFE-lined, so printing hotter should be safe.

Those kind of uneven layers can also be caused by a mechanical issue on the vertical axis, but I don’t think that would increase the risk of warping.
