How to have fun making music?

Hello dear HN Community.

I have been practicing Piano since 2017 and no matter what I did, I never had lasting fun. I was able to learn this Zelda Song and play it perfectly in metronome https://www.ninsheetmusic.org/download/pdf/1451

I tried to learn improvising, but my short term memory is bad. I took Online lessons since I did not find a teacher that would drive to me. They were a technical disaster. I'm somewhat immobile since I cannot drive a car because of my disability.

Now, I want to make music and have joy. I can imagine a Song how it should sound, but I cant bring it together. I thought of making music digitally, but I'm lost. I really love classical music.

For now, I'd like to have fun with the most basic forms of music, but I don't know where to start. Piano has been frustrating because it felt like a 'spot the mistake' game. I would practice something, and stop immediately when I made a mistake and play again... Thats no fun...
