Integrated webcam not detected sometimes (asus vivobook x512da)

The problem only occurs on some boots, and it sometimes fixes itself by rebooting. I suspect it is related to the battery. It only works when I reboot with the power plugged. But that's just a hypothesis for now.

This are the relevant parts from dmesg:

[    7.055905] uvcvideo: Found UVC 1.50 device USB2.0 HD UVC WebCam (13d3:56dc)

And journalctl:

Any ideas?
