Hi Viet,

Thank you for reporting this crash. To investigate further could you supply us the following:

1. Can you replicate this crash in one of our sample apps?
2. What SDK version does this occur on?
3. What is the session to crash ratio on the Redmi Note 8?
4. Can you provide a Charles Log when the crash happens?

Regards,
