Thank you for your report!
However, this report is Invalid.
The texture pack apparently has logic for running on the Apple TV version of Minecraft, which was discontinued in September 2018. This pack needs to be updated. If you purchased it from the Marketplace, you should be able to download the latest version by returning to its page in the Marketplace from within the game. Otherwise, you need to contact the author or source of the texture pack to obtain an updated version.
(Marketplace versions should be kept up to date by their authors, but if you can't get a working version, try contacting the author. Mojang cannot fix add-ons that are the property of a third party.)
