TUF A15 screen turns red at boot

I bought this laptop in September 2023 so it’s almost new. A few days ago I had a problem where the screen would stay black when coming out of sleep mode. This morning when I booted it up and the screen had like a heavy red filter on it. Last night I played Overcooked 2 with a friend but I didn’t do anything unusual. I know it’s not a hardware problem because the colors were fine when displaying the bios menu.
Here are 2 images of my lock screen before and after for comparison :

I contacted the technical support this morning and they said they would send me an email with multiple steps I can follow to solve the problem but they must have misspelled the address because I didn’t receive it, more than 5 hours later. Sadly I remembered to call them right when they clock out and I am desperately trying to find solutions. I don’t have a second screen so I am pretty much screwed right now.

Does anyone have an idea of how to fix it? I’ll try updating the drivers but I don’t think it will be enough.

I've been going through most of the steps of that page and it didn't change anything.

However,

today at some point I opened PowerPoint and my screen turned black for a second then everything was back to normal again. I checked the night light settings by curiosity and it looks like it was deactivated while being active. I reactivated again to check and the screen turned red when it was on, and back to normal when I deactivated it. It was so obvious that I didn't bother to check and I didn't know it could be so extreme when turned to the max. I feel so stupid right now. The curious thing is I didn't activate it in the first place, or it was already activated but I didn't touch it. I'm glad the problem was that easy to solve. Thank you for your help, at least I got to learn some things.
