Help: Error updating the app, it closes

Hello community!
Menses ago that I did not update my kodular app and now it gives an error and I do not understand what the problem may be. The only thing I did was change some icons, texts.
Now the app installs, opens, but after splash it closes directly. I don’t understand what may have happened.
I attach the apk and the project. app mercado42 – Google Drive
I appreciate if someone can guide me in detecting the problem.

please share your blocks

Thanks for your comments.
There I am reading, I had not found that publication.
It was the title of the screen, I already filled it out and now it’s fine.
Thank you!
