LittleBigPlanetTM Mash-up doesn't update at PS5

I bought the PS4 Minecraft to my son. It has been installed at a PS5.

When we try to build the LittleBigPlanet world from the LittleBigPlanetTM Mash-up Pack, we're asked to update the pack.

After updating the pack the installation doesn't works. It seems that the updating is aborted.

Could you check if there is a problem at the updating of the LittleBigPlanetTM Mash-up pack?

Tks for your attention,
