Minecraft took away my texture pack out of no where for presumably no reason

I don’t really know when it happed but I was starting a new world and I wanted to use the pure bd texture pack I had bought but when I went to go select it, it wasn’t there I went to the storage settings and it wasn’t there either and when i reset purchases it still wasn’t there so I went to the market place and it says I didn’t buy it even though I did.
