My front and rear cameras are malfunctioning

So I recently replaced the screen on my galaxy a31 and since then I've been having some really weird issues

The main rear camera has been slowly deteriorating and over time it has been getting worse and worse at focusing, it was fine the few days after the repair now it won't even focus anymore

Now I'm having issues with my front camera, face recognition is completely non functional, it will just say the camera failed to load, I go onto the camera app and my front camera works absolutely fine

Is anyone else having similar issues and does anyone know how to fix it, thanks!
