Sustained beep when trying to heat up Ender 3 Printer

https://youtu.be/-4uy3G9UcQ4

Trying to print on my Ender 3 V2. There's no warning or anything on the screen. It only does it when I heat it up (either when selecting a model to print or doing what I do in the video). If I press cooldown, the beep stops. It doesn't seem like it stops anything from happening, it just makes the noise. I haven't made any modifications to the printer or replaced anything. It was working fine a few days ago, I let the beeping go for a few minutes and nothing got hot that wasn't supposed to and no odors or anything were released. Tried updating the firmware after this video was taken, with no luck. Any help is appreciated, thank you!
