CR-10 Max

I also recently bought a large printer, a CR-10 S5, and I haven't printed with it yet but what you're saying is very concerning.

Maybe you can change the glass bed on your printer? Event if the aluminum plate that it rests on is bent at the factory a new glass bed on top of it should be straight. You can get a glass bed at a local hardware store for cheap.

If the new glass gets bent then place thin metal strips around the the aluminum plate to straighten out the sides of the glass bed.

I recently replaced the aluminum bed with a glass bed and so far the results are amazing. I don't even have to put adhesive down as the PLA I am using sticks perfectly. The problem I had was using Creality's slicer software. I switched to Cura and that solved a few issues. The next issue is bed leveling which has been a nightmare. I can get it for a couple of small prints but if it spans over any size at all, it is tough.
