I can tell you that you are (probably) not alone. I don't study film but I do use up my free time editing and restoring films, sometimes trying to "fix" their botched editing or directing, and I've been in your position, specially this past year.
It started out that I never managed to finish a movie, which then evolved into not watching movies at all (0nly working on them, which is kind of ironic)
I can only say this, if a movie is bad, then it's just bad and you shouldn't blame your criticism for not being able to enjoy it. You need to find interesting movies, for example, I didn't watch any major Hollywood movies from 2019 because I had that same critical mentality which I felt would undermine a good film, same thing with Dunkirk. I've heard very good reviews but I haven't found the right place and the right time to watch the movies I want.
I would advice that you either take a week-off digital/physical media, distract your critical mind and do something with your body to focus that energy somewhere else. Say, take a week to do things you haven't done before, then at the end of the week, sit back and watch a movie. You'll realize that your hard work from that busy week will act like a carrot and stick situation you know? Either that or take alcohol and or drugs in your next viewing, but that's a different subject when it comes to the movie experience.
Oh also, have you tried watching other types of media? Say, a stage-play? I was surprised last night while watching a rerun of Alegría by Cirque du Soleil and I can say that production (talking about directing and acting) is very unique and it revived my inner child curiosity, specially the opening act
