Back camera not working

I got this phone 2022 winter and everything was great everything worked perfectly but then in February 2023 my back camera stopped working and since then it has not worked at all, my front camera works perfectly but when i switch to back camera it shows a blank screen. I have had times that the back camera starts working again but it lasts only 1 hour and then it shows a blank screen again. The camera doesnt work in any app, ive tried everything. Ive tried closing the camera app, resetting the settings and switching thru the cameras. My camera works only on slow-mo 0.5 zoom and 3.0 zoom and on time lapse. The camera works in only one app and its the Home app. I dont know how to solve this problem. It has been almost a full year that my camera hasn’t been working. Any solutions?
