Upon installing Minecraft for the first time on my Xbox series x I attempted to install all of my previously owned texturepacks (individually), upon doing so sometimes I will be compleatley stuck at the second window that says IMPORTING after downloading and soon thereafter the game will freeze and shut down.

Other times whilst hovering over the download button in the Minecraft store and activating it, it reads that the pack I'm attempting to install is 0mb and attempting to install it again freezes the game and closes the game soon after. (There seems to be no observed pattern in which texturepacks are responsible some work and some don't, upon reinstallation of the game again other texture packs that were giving me issues could download and others would not and would crash my game)

Another time I went into the settings to turn off auto update packs incase that was the culperate and upon backing out of the settings menu it came up with a window usually associated with downloading content, and read as follows (I cannot recrate this state and from memory this is what I seen) ... Updating packs 106565198 of 1.

Obviously that is a rediculous number I certainly don't have that much content, unsure of its implications.

I attempted to re install numerous times and still is an issue. 

In summary...

I switched very recently from the Xbox one X to the Xbox series x, I installed Minecraft, I went into the store to try and download my old texturepacks (I've not imported any old world's to the game at any point incase relevent) and utter bedlum ensues. Some texture packs will install, others will not and freeze when it comes to the importing "phase", other times it will not download at all and read that the pack that I'm trying to install is 0mb after which the game freezes and crashes.

Possibly unrelated issue, the store itself is incredibly buggy, seems jittery and trying to navigate through the store can be quite a pain. 

I have a wired Ethernet connection (fiber optic) not the issue here as my connection was completely fine upon doing this.
