Red Tint on every model materials after upgrading existing project to URP

I have tried upgrading my existing project to URP many times and every time all my models have a red tint after upgrading to URP. I have tried upgrading from unity 2020 and unity 2021 to URP but the issue is the same in both cases.

Here is before upgrading to URP:

Here is after upgrading to URP:

My models are imported using Blender with .blend extension. Hope to get help from anyone soon! And thanks in advance!

Have you any post processing volume in your scene ?

This also may come from your materials, you may need to reset their colors if you changed them.

I had post process volume 2 before upgrading to URP, but I think the problem is with my materials. Can you tell me how to reset them?

My materials are imported from blender, so I cannot edit or change them through unity. How can I fix the red tint on my blender models?

I cannot edit materials as you can see in picture
