Nik 6 Color Efex Photoshop Palette problem

I have a problem with launching Nik 6 Color Efex from the Palette in Photoshop Elements 2024. The other Nik applications open correctly. The standalone Nik 6 Color Efex application also works. I have already reinstalled PhotoshopElements and Nik Collection. This did not solve the problem. Error message in Polish:
“Ta funkcja obecnie nie jest dostępna” (“This feature is currently not available”)
