Textures turning cyan

Hello everyone,

I was hoping someone could help me with an issue.
After we upgraded to Unity 2019.1.02f some of our textures started turning cyan colored.
I tried reimporting the textures, deleting them, remaking them and nothing seems to help.

Does anyone have an idea of why this is happening?

For some reason posting the image didnt work.
