Hi, anda_skoa.
First of all, thank you for answering me.
Before reading your considerations, I was modifying the project to simplify it and thus better understand how to work with threads and why it is giving error.
You could take a look to see where I'm going wrong, the project was like this.
Thank you for your attention.
