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.

Because nobody said it yet: wash your bed with warm water and soap to remove any residue (especially oily fingerprints)
- I have washed it a couple times and was getting the same results. I’ll try again just in case.
  
  Better solution than water and soap: Clean it using isopropyl alcohol on a clean rag (no paper tissues). Works much, much better.
  
  The last time I cleaned it I used 99% isopropyl alcohol, hoping to get a good clean on it with no luck. I’ll try using a lower percent next to see if that changes anything
  
  get a box of the alcohol prep wipes, they wont leave residue and you can one and done them while taking away the almost invisible film that will build up after a few uses
  
  I have a box already but never thought of trying those out. Thanks for the tip!
