Welcome to the community, @Mateus_Mossmann! Thanks for reaching out.
Is this happening with multiple apps or one in particular? And when did you first notice the issue? Based on what you've shared, it sounds like the state of your app may have been overwritten by an empty save payload, similar to what is described here.
You mentioned above that you've already tried reverting to previous versions, but does that include using the _historyOffset URL parameter?
