Blendshapes is broken in Unity 2021

So I used to use Unity 2020.1 and everything was good but I had to upgrade because I needed lens flare SRP for my game. Now I don’t know if this is a bug or what but in Unity 2021.2.17, blendshapes does not work properly during runtime. The weird thing about it is if my camera is away from the model I can modify the blendshapes with no problem but if the camera is looking at the player during runtime, the blendshapes return to 0 and will not move. I never had this issues in older version of Unity prior 2021 versions. Because of this I cannot use my character facial expressions and make my character customization work and I cannot go back to previous versions because Unity does not support downgrading your project. Have anyone else ran into similar problems?
