When using \_switchCamera method for camera mode change, fatal exception occurred.

This exception happened in Android S10 Plus device when switch from front to rear, from rear to front,  
then from front to rear.

The latest version, 1.84.0 has the same issue.

Is there anyone who knows other work-around solution instead of using \_switchCamera?
