## Your environment?
> LINE SDK version 5.10.1
Andorid version -12
Phone Model - Oppo Reno5 A

Start by reproducing LINE login on Android 12 with SDK 5.10.1 on the Oppo Reno5 A, then trace the failure through LineAuthenticationController, AccessTokenCache.java, and StringAesCipher.kt. Investigate the reported KeyStoreException during token encryption; done means login completes without the crash and the access token is saved successfully.
