What's the log of MMKV when that happened?

Your detail logs. As much as possible. For how to forward MMKV's log, you can checkout the wiki on each platform. An crash issue will be ignored & closed in a week without logs.

在Application#onCreate()中初始化的MMKV 线上用户部分会出现ANR

According to your stacks, the ANR is inside a system lib art::JNI::GetStringUTFChars(), nothing we can do about it.

有什么办法避免吗，现在每天有1000多次 @lingol

No idea. It's not mmkv's problem.
