Having problem with manual focusing and digital zooming in certain condition.

I'm working on with high-speed camera with Google Pixel 4a smartphone. When I'm setting the manual focus and digital zoom for 720p 120fps, the code runs smoothly. However, when I try to run the same code with 1080p 120fps or 720p 240fps, the preview stops and crashes when new touch input is in or I try to start the recording.
below there is log when I tried with 720p 120fps:

I have no idea why the code have problem running on different setting, while it is working fine on certain setting. It seems like the inner settings are the same, except for resolution and fps. For the information, I set the sdk on 31, build tools on 22 to implement digital zoom. Can you help me with the manual focusing and zooming? Thank you.

Start with CameraFragment.kt at the reported onError callback around line 1211 and the high-speed session cleanup around line 755. Reproduce the 1080p/120fps and 720p/240fps cases on the Pixel 4a, compare them with 720p/120fps, and trace the camera error through the focus, zoom, recording, and session lifecycle. Done means the affected settings no longer produce the reported fatal camera crash.
