Edit:
I guess misunderstood some things. anx7688 seems to be a USB controller. The modem is separate from the SoC and is connected internally via USB. But maybe it’s not a problem with the modem in this case, but with the controller.
That’s my bad, I should’ve specified that anx7688 is the USB-C bridge driver controlling all USB devices along with the modem.
In this case the modem is being effected by the USB charging state & USB-C peripherals over CC pins from anx7688.
Your other issues are very likely tangentially related to the modem error messages caused by an underlying issue within the anx7688 USB-C bridge driver’s controller.
