Feel like I’m just failing at my job, any advice?

I started a new job about 2 months ago within the same company (been there almost two years) but on a different team, and up until last week things have been going well. I just now feel like, at least with my current work, I'm stuck and too afraid to ask for help out out of fear of backlash for not approaching the problem the right way. It's making me way too anxious, because I just feel like my general ability to code trace and logic my way through code to figure out problems and solution fixes is just wrong. I feel like I'm just wasting hours if not days of time trying to figure it out myself, but it feels like that's the only thing I can do. Gonna try and get help tomorrow, but I'm just looking for some advice on what to do I guess.
