I was in exactly this situation and I actually bought a handwriting book and "re-learned" how to do it by working through the book and focusing on writing with my shoulder instead of my wrist. I saw immense improvement in three weeks or so, and doing handwriting practice was also extremely satisfying and a good mental break after a day of coding.

I used this book, no affiliation other than I liked it: https://handwritingsuccess.com/write-now/
