Update MCU to 319 version or later, using Windows. It'll help. Had the same problem.

I bumped into the same issue on 3.7.17, reboot didn't help, ended up updating the BIOS to 342 via EZFlash and it seems fine now, but it's probably just a coincidence.

Edit: the issue came back. BIOS update does not fix it.
After another reboot, it works again, but it doesn't always work after a reboot, it seems persistent.

Edit 2: after updating MCU firmware to 320, it doesn't happen anymore. But updating MCU firmware is impossible without booting into Windows. I know that's on ASUS, but it should work on Linux, too.
