[REALMS-11913] Bedrock realms refuse to load if I use Marketplace addons

If you are experiencing this issue, please comment with the specific add-on(s) (exact name and creator) that you are using.

When I add Marketplace addons (such as "RealismCraft" or other official Minecraft contents like "Minecraft Realms celebration map") to my realm, the game gets stuck at the loading screen when I try to join. The loading bar doesn't even reach halfway before it stops. After a few minutes, I receive the error message: "Failed attempting to join realm."

I reached out to a few other players on Discord to see if they experienced the same issue. They confirmed that they also cannot join their realms when Marketplace content is added. Interestingly, ONLY realms with third-party addons load without any issues.
