I have the same problem playing on my Xbox X, trying to play in split screen. Tried quite a lot of workarounds, but everything failed. We basically can not play and enjoy the game until it is fixed. Here is some information, which I have gathered during a troubleshooting session.
Steps to Reproduce
Launch Minecraft: Bedrock Edition on the Xbox console.
Sign in with Player 1 (Host) and load a world that has a Marketplace Add-on (with custom blocks/items) applied.
Player 1 can confirm the add-on is working correctly (custom items have their correct textures).
Player 2 (Local Split-Screen Co-op) joins the world.
Player 1 or Player 2 places a custom item/block from the add-on.
Observed Result
Player 2 cannot see the custom item/block; it is invisible (missing texture/model).
The problem immediately affects Player 1 (Host) as well: any newly placed custom blocks also become invisible to the host.
Items already placed before Player 2 joined remain visible to the host, but not the second player.
If Player 2 leaves the game, the issue persists for Player 1 for the rest of the session. The host must fully close and restart the Minecraft application to fix resource loading.
Expected Result
Both Player 1 (Host) and Player 2 (Split-Screen Guest) should be able to see the textures and models for all blocks and items from the active add-on.
The game's resource loading should not break or corrupt upon the second player joining.
Workarounds Attempted (and Failed)
Having Player 2 exit and re-join the world.
Removing the add-on from the world, saving, and then re-applying the add-on.
Checking and changing Video/Graphics settings (e.g., Fidelity/Vibrant Visuals).
Deleting and re-downloading the add-on from the Marketplace.
