Refrigerator left cracked open for 2 hours

Ok help, I’m very cautions when it comes to eating things, and when my mom left for work at around 7:45 and I woke up at 10:15 am, I noticed the fridge was a little cracked open, not open enough to see the stiff inside, but still cracked open.

Is everything In there okay? I have almond milk that I wanted to have in a while and now I’m scared! Lol

I felt a few things, and they were still a little cold, kind of when you go to the grocery store and you stop by somewhere really quick after (if anyone gets me)

HELP PLEASE 😭😭😭😭
