Problem with my clips: permanently slowed down

Hey people, so my friend (Mac) just started using AE and her clips are permanently slowed down. When she looks at them from her media player the file is perfectly fine but as soon as she drags it into AE it's just slowed down. I'm editing on ae since, like, 2022 (Windows) but I've never had that issue before. Btw I don't mean the audio playblack glitch (when it's not fully rendered yet) by slowed down. It's just permanently on slow mode. We still don't know what to do. Thanks
