I have a Mi 9t Pro and Xiaomi.eu 21.4.7 installed. Front camera opens but closes directly and camera app crashes. I checked connections of camera cable internally, was fixed normally.
Also can't open CIT to calibrate
Yes I downloaded the updated rom. I installed it yesterday (dirty flash)
I also did this "I cleared memory; ran Cleaner; cleared Recents; cleared Dalvik and cache; deleted /data/system/package_cache folder; (and deleted /data/extm folder) "
On first boot front camera works good and stays up; But today the front camera pops up but goes down immediately and camera app closes too.
Here is the logcat I did. I did the front camera open at 21:30
