Description

There are crashes in some Meizu phones, such as M5 note, PRO 7 Plus and so on. The system version is Android 7.0. The log is:
`Fatal Exception: java.util.concurrent.TimeoutException: android.security.keystore.AndroidKeyStoreAuthenticatedAESCipherSpi$GCM$NoPadding.finalize() timed out after 20 seconds

Research direction

Start with the AndroidKeyStoreAuthenticatedAESCipherSpi$GCM$NoPadding.finalize() stack entry and the KeyStore.abort call shown in the report. Reproduce the crash on the listed Meizu Android 7.0 devices, determine the affected operation, and verify that the resulting change prevents the timeout without breaking AndroidKeyStore behavior.
