We installed Brazil patch 0 on one of our sandboxes to do an evaluation. We started seeing an error pop up in SOW and other areas. "Execute operation on API 'Glide API: string utilities' from scope 'Field Encryption Starter' was denied. The application 'Field Encryption Starter' must declare a cross scope access privilege. Please contact the application author to update their privilege requests."
Some buttons didn't render, although I can't confirm it was due to this same issue. Brazil patch 1 did not resolve it, and we opened a case with ServiceNow. They rolled it into PRB2078372. Field Encryption Starter is a private application, but I could see where there were several cross-scope privileges defined as part of the application even though I couldn't edit or add one in that scope. I eventually tried to repair the field encryption starter application, and it resolved the red box and the buttons came back. We have asked if this is the permanent solution or will we see this come up again. SN is still looking into it at this time. But in case anyone else sees this box, you might try the repair yourself.
