Could not launch "App"

I'm getting this error message after a successful build to my phone: The operation couldn’t be completed. Application info provider (FBSApplicationLibrary) returned nil for "com.example.app" It's a sticker app & it builds to the phone, however, the buttons that access the stickers are present, but the stickers are not there. Has anyone else encountered this issue, and if so, were you able to find a solution and would you be willing to assist me? Much thanks in advance.
restarting the device helped me
