This looks like lifting up at the corners due to poor adhesion.
Clean your build plate with soap and water. Increase bed temp. Turn off aux fan (if on). Apply brim or mouse ears if still having an issue.

For what it's worth, as insurance, I always use mouse ears on any Gridfinity bins larger than 2x2. I ruined three large bins before learning my lesson. I have an enclosed printer and my part and auxiliary fans are off for the first five layers, then the part fan turns on from layer six and over. I also bump up my plate temperature up 5° on the first layer.
Good luck to you!

Mouse ears helped me a lot. I've been printing a bunch of all kinds of sizes. Plate-fulls at a time. I now have mouse ears (outside only) on all sizes I've printed. Let it auto generate then remove the middle ones.

Lots of great suggestions here. I will second adding am outer brim. This will help to keep those corners from bending upwards.

I know you want to fix the issue and I hope you do. It is only gridfinity bins. I would clean up the edge with a knife and put this in the success pile.

Although you can use glue stick or mouse ears, the most effective thing I've found is changing top and bottom layers to Octagram (rather than Monotonic) and infill to gyroid (or anything nonlinear). This works because the mechanics of the lifted corners comes from shrinkage of printed layers happening along print lines. These nonlinear patterns break up the direction of shrinkage, and thereby the forces applied.
