Suggested Solution

As per the plugin code earlier 9.2.4 version in FlutterSecureStorage.java class, you removed try catch code block into run method
Check this link to see difference.
basically to mitigate this issue, check around onDetachedFromEngine method as well.

Possible Steps to reproduce:

• add app in background
• app app in foreground
• try to hit 1 storage write call

Let me know if you need more details to resolve this as soon as possible.
