Hi everyone, i recently opened up a project that i stopped some time ago, before all the updates.
In the project i used AppCompat Checkboxes and switches and as soon as the layout loads up the app crashes.

I tried to remove the checkboxes, switches ans library, and it doens't crash anymore.
someone has solutions?
