密钥库无法加载ID为_androidx_security_master_key_的密钥

我正在尝试使用 masterKey 来加密共享首选项。但是，有时我的用户会由于来自密钥库的 invalidKeyException 而崩溃。我无法在本地重现这个 =

java.security.KeyStoreException: the master key android-keystore://_androidx_security_master_key_ exists but is unusable
Caused by: java.security.InvalidKeyException: Keystore cannot load the key with ID: _androidx_security_master_key_


任何想法为什么会发生这种情况？

val masterKey = MasterKey.Builder(context)
.setKeyGenParameterSpec(
KeyGenParameterSpec.Builder(
MasterKey.DEFAULT_MASTER_KEY_ALIAS,
PURPOSE_ENCRYPT or PURPOSE_DECRYPT
)
.setBlockModes(BLOCK_MODE_GCM)
.setEncryptionPaddings(ENCRYPTION_PADDING_NONE)
.setKeySize(MasterKey.DEFAULT_AES_GCM_MASTER_KEY_SIZE)
.build()
)
.build()
securePrefs = EncryptedSharedPreferences.create(
context,
PREFERENCES,
masterKey,
EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
)
