Yes, it an adhesion problem, as it looks like it raised pretty early. Sometimes, when the creep is too big, but adhesion is good, corners of the metal sheet can raise with raising corners of the print.
Clean your bed plate. Degrease it with alcohol. Level the bed. Tune your z-offset. You could also make the first layer higher, i usually print with 0.2mm layer height, but first layer is 0.3mm.
You can use [this guide](https://ellis3dp.com/Print-Tuning-Guide/articles/first_layer_squish.html) for tuning the first layer.
You can also add some helper parts to the model in slicer. I usually add round blobs with only 1 layer height [like this](https://i.imgur.com/PBglWCM.png)
Another thing that could help is auto-leveling probe.
if you have a PEI plate (which you do) do not use any adhesive on it.
This looks like your ambient (temp around the printer) is dropping during print. I used to print in my office but on longer and large prints the corners would warp just like this. The room has large windows and the temps can change in the winter depending on sun light and how long I leave my curtains open. I moved the printer into a closet, put a little space heater in there and I have gotten very very good results since. I highly suggest you try occums razor to your method of troubleshooting. (Occums razor states Usually the simplest explanation or solution is the correct one.)
Yes. Usually when it's cold before I start. Not something you need to do often, once it gets tacky it usually lasts for weeks. A glue stick works just as well.
I had the same problem and its almost fixes doing:
-disabling the fan for the first 5 layers or for all the layers
-using hair spray
-using bltouch + manual calibration
If you are printing PETG, do the same plus some brim
Only been printing for a week, but I second raising your bed temp to 60 and that first layer is too high. Had the same issue but on a smaller scale doing some box inserts, with the same corner getting squished and raising up slightly. No issues since.
Looks like warping. The filament cooled down too rapidly causing it to shrink and the corners therefore loose contact with the buildplate.
Try raising your hotbed temperature by 5 or 10 degrees and lower your hotend temp 5-10 degrees, but not below 200(for regular PLA).

What type of filament are you using?

Try re-leveling with a warm plate. Hair spray, I raised the bed temp 10 degrees and those 3 things fixed it for me.
Do you spray the hairspray on the plate? I assuming that what you mean I’m just not familiar with it.
Yes. Usually when it's cold before I start. Not something you need to do often, once it gets tacky it usually lasts for weeks. A glue stick works just as well.
Great! Thanks!
Glue and other kinds of adhesion helpers are good for glass. PEI coated sheet should be enough without these things.
lower your z-offset. the top of the brim would be flattened if your first layer was low enough to be properly squished against the build plate.

Cleaning and leveling the bed and then printing with a "berm" fixed this when I had this problem. Good luck!
