Unreal Engine crashes when I add a texture sample node

Hi everyone,
I’m using UE5. This problem only happens in the AR template project. I tried it in other non AR projects and it worked fine.
I imported some images, and then converted them into materials. The moment I open any of those materials Unreal crashes on the material preview tab. I imported only one picture and converted it, I made a new AR project, I used JPG and PNG, I tried everything and it still crashes every time I open a material that I converted. Any idea why ? Thank you.

Update: The problem seems to be in the texture sample node, if I create a new material and add a texture sample node, it crashes.
