So I was creating the design for the window.ui using cambalache and the compilation failed. The error message: 1:1 error: Can't validate the schema: 'resource:///plugins/xml-pack/schemas/gtk4builder.rng'
The error message:

It happened before my pull request was merged and before it everything was working perfectly, I have created another branch for the ui, done the merge and a push and doesn't worked anymore. I just want to fix it and make the window.ui after compiling looking like what I maded at Cambalache [What I made in Cambalache(https://i.stack.imgur.com/cWwKR.png) My github repo I am still newby using this IDE and also github, so sorry for my begginer mistakes
Well I just updated my ui using cambalache and now the program runs, but it's not loading the GtkGrid gtk-multicalculator, but the buttons are next to each other
