Weird colors (pink/violet) with baked lighting and Raytracing reflections

I have a problem with my project in UE5. After baking lighting (with RayTracing reflections) sometimes I have this weird colors. But sometimes not. After opening project in editor it has this colors but it is OK after few seconds.
This problem occurs with packaged game too. After opening game sometimes its OK but sometimes it has this colors and you need to quit it and open it again.
And problem occurs with moview render que too. Sometimes it has right colors and sometimes this weird.
Dont you have any idea where should be a problem? I never had this before. Thank you

Please, anybody can help with this?

Thank you very much!
