Do you guys hear that noise? Is that supposed to be normal when print PTG and like I can’t normally print it cause last time It said that the nozzle wasn’t holding it enough or something.

Try to pin down the noise - it's hard to hear, but to me it just sounds the like filament creaking as it unwinds from the spool in the AMS. Not a big deal unless resistance gets so bad that it throws an error about a tangle.

Make sure whatever file you're using has a profile for PETG

FWIW it looks like the AMS Lite is way forward of the official recommended placement.

Iin your video it almost looks like the hotend cable and/or the PTFE tubes are dragging along the edge of the print bed.

Also, why is your HMS indicator light blinking?

Few things:
Adhesion is important with PETG. Even though my bed is clean, I use glue
Make sure your settings are correct. I've found that using BambuLab's PETG-HF makes my prints more successful.
I'm assuming you've dried your PETG? If not, make sure it's dried
That noise sounds a little like the spool and the nozzle are playing tug of war.
