Small challenges can be a good way to practice and improve - i felt much more comfortable after doing a few days of advent-of-code in gdscript last december: https://github.com/russmatney/advent-of-godot (note this project is still on 3.5, but things haven’t changed too dramatically for this project, as there’s not much ui/node interaction, mostly just code)

I’ve struggled a lot with it too but over time it becomes natural again

I started by following some YouTube videos. Follow a simple tutorial. At then end EXTEND the game a little with your own ideas. Add a new power up, make a new level, make a new enemy, make a new weapon type, something.

Once you already have an established framework for a working game by following the tutorial you don’t have to worry so much about the bugs. This builds confidence.

Also don’t underestimate the built in documentation and search. I’ve been using godot for 2 years now and I reference the docs almost every time I code to check if a certain method exists, or how to get a certain property.

These videos may be old now, but heartbeast on YouTube had a few great series for godot 3.x
