Camera forces closes

I'll try to keep this as brief as possible. Yesterday I flashed LineageOS 16 + GAPPS on my MI 8 which at that time was running MIUI 10 Global without any issues. However, after flashing Lineage my camera started acting up even though everything else worked like a charm. Everytime I tried to open my camera app, I would get a message saying "The camera device encountered a fatal error" which I could report or dismiss. Both resulted in the app crashing to my home screen after which I repeated this process 3 times, but the problem remained. Someone mentioned that the GCAM app that I was running was designed for Pixel phones and wouldn't work. I used TWRP to delete CameraGoogleLegacy which worked. I then installed a camera app but again the camera would give a black image (front and back). I then repeated this process, but I tried installing the Pixel Experience ROM this time instead of Lineage. Again everything worked flawlessly, except the camera.
Then someone asked if I flashed the correct global firmware & vendor before flashing Lineage. I wasn't too sure, so I decided to flash MIUI 10 global 10.2.3.0 again. Much to my surprise, the stock Xiaomi camera app now doesn't work anymore either, nor does the Gcam port I was just using yesterday on the same ROM.
Any help would be greatly appreciated
Thanks!

Question Device freezing in MIUI 13 all versions and variants

After updating to MIUI 13, I randomly have freezing issue (when scrolling tiktok, playing game, watching youtube, etc.) which sometimes fixes if I wait and the system shows notification of "The *app* stopped working" or something, and many other times I can only force reboot the phone (by holding the power botton until it reboots).
The issue never occured on MIUI 12, only on MIUI 13 from the first version untill now. So overtime I downgrade the ROM or change it to other variants such as global version (the issue also occurs in other country's variants of MIUI 13), hoping that the bug is fixed everytime there is a newer version of MIUI 13 of Indonesia but it's never been fixed.
I report many times through the feedback and service but they only suggest to keep the RAM and memory managed, and to charge the phone in time, which don't solve the issue since I have plenty of internal memory space available and use the phone the same when I'm on MIUI 12 (also how the hell do I charge it in time?!).
Does anyone have this issue as well? And how do you fix it other than to downgrade or to change to custom ROMs? Is it better to wait till MIUI 14 comes out than to downgrade it again? Sorry for my bad English.
i have the same issue though, I'm still hoping an update for this kinda issue because it's really annoying. I'm not sure for install custom rom will fix it, or it does.
I ever thought that downgrade is the only way to do, because when I use miui 12 I didn't get any of bugs and issues.

MIUI 13.0.8 just came out a few days ago for my region, but I won't upgrade it at least until MIUI 14 comes out.
Installing custom rom does fix it. I tried Pixel Experience once and never got the bug, but I didn't quite like the overall appereance so I decided to just downgrade it again to MIUI 12.5.5.
Yes. I have had this EXACT same issue, too. factory reset did not resolve. Redmi Note 9 Phone is all but useless now. Can use for a few minutes at a time, before it freezes. Miui 14 should be around the corner now, but I'm not hopeful.

MIUI 14 also does not resolve the issue for me, so downgrading is the only solution (not even MIUI 13 and 14 based custom rom fix it). But some people from RN10pro forum got it fixed after a few updates. Here are some suggestion I got from there:
1. Check if your SD card is dead, simply replace it or take it out.
2. Change your system to light mode.
3. Disable the memory extension.
Some people got it fixed after doing one of the above suggestions but not for me.
