Lock screen Clock widget not showing

edited September 2020 in Others
It's really annoying not seeing the time when ai wake up my phone, not showing the clock widget in the lock screen. So I've looked into all kinds of forums here, I already did everything: Update Clock and Weather, clear data and cache for Clock, manage space of ZenUI Launcher, rebooted my phone a hundred times, and the clock widget in my lock screen still doesn't show. BUT, when I reboot my phone, the clock widget shows only for a few seconds, and then it disappears. The only thing I didn't try is the factory data reset which would be my last resort for this, but if there are still other ways, please let me know.
