1. capture image with 4624x3472 res
2. user resetCamera to decrease resolution to 1280x720
3. capture image and observe it was captured
4. use resetCamera to increase resolution to 3840x2160
5. observe that application is unable to read frame and gets stuck

My modified code to illustrate this
https://github.com/edward-ardu/libcamera-cpp-demo/tree/9226ee5eed4c3ee852ae28ad9a93afe3aba5c35f

I ran several resolution change scenarios and concluded that the problem is only when next resolution is equal or larger than previous:
1280x720->1280x720=fail
4624x3472->1280x720=success
1280x720->3840x2160=fail
4624x3472->3840x2160=success
1280x720->4624x3472=fail
