Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

2. Also, please try "the Factory Reset"
Settings>System>Reset options>Erase all data(factory reset)
Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
3. If the situation remains the same after performing the Factory Reset, what you described indicates high possibility of slightly faulty hardware, any firmware update/flashing may trigger the symptom. Please turn on auto-backup or backup your data from time to time. If the device does not encounter the auto shutdown frequently, you may keep your normal usage. If the device starts to encounter the auto shutdown frequently, e,g. from once two week to once two days, please bring your device to the nearest repair center for further device checking.https://www.asus.com/support/Service-Center-All-Countries/
