I definitely feel this a bit. I had to onboard onto Ruby and Rails recently and I truly hate it.
That being said, the reason why it wasn't an absolute nightmare for me is because I have good foundational skills and I genuinely enjoy software development. These two things have made it very easy for me to onboard. I also strive to understand how the internals works, and that speeds me up tremendously.
I'd encourage you to understand how the internals of Vue work. That way when you're working, you don't have to think about Vue itself, and just about what you're working on. If you really do feel like you're getting "dumber", start writing stuff down! The only way to truly never forget something is to understand it deeply, as if you can explain it to a 5 year old.
Anyways, this is my advice. I'd be happy to chat offline if you want some more advice (in my early 30s).
