Dear Friends,
Actually am facing the same problem with my Google Pixel 3a XL device with these issues:
1- When turning camera app to video mode I can take the video everything runs smoothly, then a message pop up that camera app is frozen and have to restart the device to operate well.
2- After restarting the device when opening camera app, it is black and nothing can do for both picture and video mode and gets flickering screen.
3- when opening the media to play back the video it says the file is corrupted and can not play it.
4- device's vibration disappear, I have to reboot it three times to operate well.
SO camera apps works fine as long as you do not switch to video mode.
Looking forward for the issue to be fixed in 24.04 OS.
