g14 2024 randomly shuts down when charging with USB-C

I use the g14 primarily as a workbook, as I bring it around. As such, I use an Anker 120W charger with Anker's 100W type-C cable very frequently with the device.

Recently, the g14 has started to randomly shut down when I'm charging with type-C. I don't know if it's a coincidence, but often it's when I'm using the Anker charger to simultaneously charge something else as well (i.e. my phone).

Has this happened to anyone? I bought this for more than 30 days so I can't return it to Bestbuy, so maybe I need to contact Asus directly.

Any help is appreciated, thanks
