First, you probably don’t need to turn the breaker off and on to reset it. There is an air gap switch on the bottom of the device. If you pull it out, power to both the switch and load/fixture are cut, so pulling that out and then pushing it back in is probably a lot easier than going to your breaker.
But obviously, more importantly, this shouldn’t be happening. If you do some searching, you can find some users with similar experiences and maybe find some ideas that will work for you. If your switch is totally turning off, this thread may be of interest: Dimmer Switches | Random Shut-off Issue | Data Collection Thread (but there seem to be two separate issues, one where the switch itself crashes/turns off and usually needs to be reset and the LED bar is usually off or dim, and another where the load just gets switched off and turning it back on is an easy fix; it’s not always clear to me which people are talking about or if everyone’s symptoms are the same for either).
