Multiplayer and Marketplace stopped working after updating to 1.21.81 – Error D_oo10 and hosting failure

After updating to Minecraft Bedrock version 1.21.81, multiplayer hosting and Marketplace stopped working correctly.

When I tried to invite a friend (same version) to my world, we both received this error:

“There was a problem with your connection. Multiplayer hosting has stopped and will need to be restarted.”

The Marketplace also does not open, and shows error D_oo10, preventing me from changing skins or accessing content.

These issues did not happen in the previous version. Everything was working fine before the update.

I tested with both Wi-Fi and 4G, and the connection is stable.

I’ve confirmed that multiple other users also reported similar problems after updating to 1.21.81.

Please investigate this bug. Screenshots are attached.
