AEADBadTagException error on user's device causing Mobile app to not open

Question

User I have in closed testing of an app uninstalled our app, and re-installed it via the Google Playstore app link. I pulled their bug report off their phone.

I'm pretty sure this (snippet below) is the source of the problem. Has anyone encountered this? How would I go about troubleshooting this error?
