Print refusing to stay flat in corners

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.

So I gave it another try with the black filament after doing some additional adjustments and was still getting the same issues. I then swapped to a brighter filament so that I could get a better picture and now it’s laying perfectly flat. I’ll let it continue printing to see if any other issues pop up, but it’s weird that one filament was lifting but an older spool works fine.
- Gave it some time to print and unfortunately it lifted up again. Going to wait for the thermometer to come in and see if that corner is heating properly
- Different brands/colors can have totally different additives that affect bed adhesion - might be worth checking if that black filament needs more thorough drying (even if you used a dryer, some PLA needs 6+ hours at proper temp).
