Objects that are imported are not able to get the materials in the editor. prefabs, materials ale are in pink color

if your renderer is URP then you can filter by materials and select all of the pink materials and go to EditRenderingMaterialsConvert Selected Built-in Materials to URP

if you are using #Built-in renderer than select Standard from the materials shader which are pink. For pink materials which are for particles you can select from the shader ParticlesStandard Surface.

Yeah, the problem was solved
Thank you!
