Minecraft 2016 festive mashup map not loading

Good Day, there is a problem that did not happened before, i bought the 2016 festive mashup on 2016 and it worked correctly until the nether update, since then everytime i tried to create the world that is included in the 2016 festive mashup it just says that there has been a problem and the world couldnt be loaded. Also everytime i try to use the texture pack that comes along the map and skins it just does nothing, when i use that texture pack it just appears as the default textures, i dont know if it is because of my device (Samsung A10s) or if it is another kind of issue but i would like to have a solution because i have paid for this mashup and i cant even play it, i have tried to use it on diferent devices but i had the same problem so i dont know what else to try. I thought it was because of the version so i waited for the 1.17 to drop but nothing changed so i hope you could find a solution to this problem.

Thank you so much for reading
