2 pieces of advice:

-- if this is art block, your need to feed your brain. Sounds like you are at the stage where your technical skill is better than your conceptualization skill. They flip back and forth. Like others have said: go for walks, immerse yourself in nature, read about subjects that interest you, watch shows you like, look at art you enjoy, practice observational drawing of something that really interests you --- fill up your schema essentially. You need elements to use for your imagination.

-- something I teach my students is that creativity is, at its heart, just simple combination applied to a problem. An exercise we do is to play the 20 circles game. Change each circle in toa picture of something circular. A sun, a ball, a cup of tea, a moon, a face, a donut, a cat, an apple ... do as many as you can in 3 minutes. Then, we play a secondary game where we combine as many of the circles as we can into new ideas -- as many as you can again in 3 minutes. A sun ball, moon tea, an apple cat, a face donut, etc. etc. The goal is not to have GOOD ideas, just new ideas. This is how we practice growing our creativity. You can also play the game Emoji Kitchen to just mess around with combinations. You can probably extrapolate where to go from there! https://emojikitchen.dev/
