How to fix regular blackout of Touch Bar?

I have a 13-inch 2017 MacBook Pro (Intel Core i5) with a Touch Bar. I've noticed, that it occasionally disappears, and then after a few days re-appears. It is not a hardware problem, as [killing the touch bar server](https://discussions.apple.com/thread/254759141?sortBy=best) is affecting the Touch Bar: The buttons come back in a 'grayed out' colouring, but they are not affected by touch sensory. Unsure if the following information may be relevant: My behaviour, when I go off, is to close the lid of the computer overnight. I don't leave my computer powered at 100% battery and never let it run down to 0%. (If the Touch Bar has its' own battery, it *should* always be powered.) Another observation I've made is, that it seems to be most of the time browser (Chrome) - or more specifically YouTube related, but it also once happened when I did not have the browser open. Usually the touch bar re-appears the next day. The question is, why does this happen, and what options do I have on preventing it, without sacrificing quality of life (for example, without always turning off Mac)?
