"The naturalist" Add-on crashes my game on Ps4 and Ps5

Bought "The Naturalist" Add-on in the Marketplace for 7,99€. Everytime i want to create a world with this Add-on my Game crashes. I dont have any other Add-Ons and its also my first one. I can create everything normally without the Add-on. I play on Ps5 but also installed Minecraft on my Ps4 and tried to start it with it. On Both Playstation its not working. I screenshotted technical Details and the Error report. Hope someone can help.
