I'm not sure if it's related to your issue, but a few things come to mind and I used to blank out quite a lot as well, so I guess I'll share my experience, but I generally think that this issue is map reading based.
- Try to have an empty mind while playing, don't think about anything else but reading the map, watching the map closely. This trains your focus, but takes time. Don't worry about losing focus, just every time when it happens, remind yourself and snap right back into it, you'll lose focus less often. Minimize distractions (meditation and breathing technique can help freeing your mind before starting to play a map, google it if you don't know about it).
- Try snapping (snap aiming) onto every object, no matter the distance. This one is related to my first suggestion and how I "focus" and get into my zone. When I want to snap to every single object on a map, I have to REALLY look at every object, and the focus and precise observation that requires just automatically pushes me into the zone.
What I do notice is, that when I am focusing and reading well for the most part, I might sometimes still blank out for a different reason, when a pattern or jump is too complex and I struggle to mentally keep up / struggle to follow it with my eyes. Idk what to do about this, except practicing more and hoping that my eyes will be able to follow those properly eventually, the only thing I actively do about those cases is to instantly remind myself to look at objects properly again the second I notice I blanked out. Usually this means, that I only blank out for super short moments and from my experience, blanking out doesn't mean you'll miss, it just makes it more likely. Quite often, I still hit all those patterns and jumps that make me blank out, I just dont fully comprehend what actually happened and I'll feel like I couldn't properly read it.
- Blanking out and not clicking. I sometimes have this issue with difficult to read singletap patterns, not accurately reading how many circles there are or not being aware how many of them I have clicked, but when I try to snap to every object, I am more conscious of how often I need to click and where I am precisely "right now", that helps me actually click. I also notice that putting a little more force into pressing the buttons can help with control, but I do recommend experimenting with pressing buttons softly, too, it's harder and requires way more finger control, but gives you more stamina if you can manage that. Don't go crazy with this though, press in a way that is comfortable, but you're obviously less likely to not click if you consciously put more force into each one.
Hope this helps? You look really new though, so I'll just drop the cliche play more in here as well. GL
