Minecraft Marketplace: purchased World stuck on downloading

Using W10 on a PC; MS Store Minecraft launched via XBOX Store & Minecraft Launcher.

Updated all of the following;

Windows 10

Drivers using CCLEANER (There were 2 audio drivers).

MS Store

Ran XBOX Repair

Closed Minecraft & XBOX Store multiple times; rebooted PC multiple times.

Issue seen with another previously purchased World now stuck same as new World - tested this after the current issue appeared.

Deleted various Worlds from Storage to free space NB I have a lot of space to use yet - 700GBs.

Re in-game Settings/Storage - the new world that I was trying to download was not seen but the Skins are.

This issue never seen before by me.

Thank you for any advice.

:)
