Hi, welcome to the community!

I see that the message is looking for a package prueba. Do you have it inside the src folder?
I see that the first command you did deleted the src folder, so I’m assuming you don’t have it.

First i make a new package named prueba and then when i launch it it gives me that error.
Then i execute the commands because i found them in another topic for fix it and apparently they don’t work BUT before execute then i left a couple hours and when i came back all seems fixed so i don’t really know what was happening.
I don’t have any problem now, thanks for your time.
