Screen goes blank when pressing Button inside Designer

[Israel-Laguan]

Description:

I've made a design, but when adding a Button (blank, default), and pressing it or the name on Left Bar, the screen goes blank.

My code:

{"screens":{"1":{"id":1,"root":2,"name":"SEO KeywordsTool"}},"screenOrder":[1],"components":{"2":{"id":2,"type":"Grommet","props":{"style":{"height":"100vh"}},"children":[3,12],"collapsed":false},"3":{"type":"Grid","id":3,"props":{"align":"center","alignContent":"center","justify":"center","columns":"xlarge"},"name":"LoginForm","children":[4,6,9]},"4":{"type":"Box","id":4,"props":{"align":"center","justify":"center","pad":"small","alignSelf":"center","animation":[{"type":"fadeIn","delay":5},{"type":"jiggle","delay":2}],"background":{"color":"brand"},"round":"medium"},"name":"Tiitle","children":[5]},"5":{"type":"Heading","id":5,"props":{"color":"accent-2"},"text":"Entra"},"6":{"type":"Box","id":6,"props":{"align":"center","justify":"center","pad":"small","overflow":"auto","wrap":true,"alignSelf":"start","background":{"color":"dark-1"},"round":"small","width":"large"},"name":"Email","children":[7,8],"collapsed":false},"7":{"type":"FormField","id":7,"props":{"color":"brand","error":"Revisa si el email esta bien escrito","help":"Trata de que no queden espacios antes, en medio, o despues del email.","label":"EMAIL"},"name":"email"},"8":{"type":"TextInput","id":8,"props":{"placeholder":"Ingresa tu email aca"},"name":"emailInput"},"9":{"type":"Box","id":9,"props":{"align":"center","justify":"center","pad":"small","background":{"color":"dark-1"},"wrap":true,"overflow":"auto","round":"small","width":"large"},"name":"Password","children":[10,11]},"10":{"type":"FormField","id":10,"props":{"error":"Verifica que tu password este bien escrito","help":"Trata de que no queden espacios antes, en medio o al final de tu contrasena","label":"CONTRASENA","color":"accent-2"},"name":"password"},"11":{"type":"TextInput","id":11,"props":{"placeholder":"Ingresa tu contrasena"},"name":"passwordInput"},"12":{"type":"Button","id":12,"props":{"label":"Button"}}},"nextId":13,"version":2}
Local Storage saves my design

Console shows this message:

What is expected:

Nothing more than the normal hover/click Button animation

What it happens:

The whole screen goes suddenly blank

How to reproduce:

Save code into a JSON, upload to designer, click button. I've made the same several times in private or normal mode in Firefox ESR on debian 9, with the same result.

Apologies for this issue. It turned out to be an issue with our CI/CD pipeline. :(
It should be working now.
