I have tried everything, my only idea for the reason it doesn't work is that I mixed up the VCC and ground once
I will take a SWAG and say you fried it. It always pays to check the wiring, then check it again before turning on power.
And then you get in the habit of always buying at least two, so that you have the spare.

yeah!!!! another 3 months from china.
(Thanks for help)
Then you buy three. I have been getting stuff in less then two weeks in combined packages.

I am going to do that
Seriously? Aliexpress delivers to me usually within 10 days (for orders >10 Euro, otherwise it's about a month - there are always other interesting and potential useful things to get to that amount).
Also remember when buying cheap components: if you need one, buy 10. For the ones you destroy testing, and because there's a good chance you'll have more projects needing the part in the future.
The Wokwi simulator does not care about wrong connections. You can work on your code while waiting for the display.

Yeah, I was exaggerating, for me, it's about 0.5-1.5 months to Romania. But going to buy 3 of one component.
