I hate anything that stops me from playing the game. Stun mechanics, usually, but I also include quick time events.

The one that sticks in my mind was those dumb water mages in genshin impact. They trap you in a bubble and hold you there for a few seconds. If it's an intense enough fight, a few seconds is an incredibly long time, and you're just sitting there watching the game happen and you've lost your agency. It's worse for me because I had built shields and healing into my team to shore up my shortcomings with dodging. It felt clever, but them the game sends in this mechanic which invalidates my solution.

With quick time events, I just get annoyed at the genre switch. Don't get me wrong, there are cool enough cinematics out there... It's just... Like usually I'm watching these and thinking, "wow, that would've been fun to do, you know, myself."

Nevermind that I'm too ADHD. Like I have cats and a partner and a phone. If I get a buzz or whatever else, I might miss the prompt. Or if I ignore the buzz, whatever that might have been can sometimes get discarded in my brain.
