Title: Unable to Join World – Pack Loading Error

Description:
When attempting to join my custom world (Mining Simulator), the game shows the following error:

"There was a problem loading pack. Restarting your game or redownloading the pack might solve the issue."

This issue prevents me from joining the world.

Reproduction Steps:

1. Open an pre existing world with custom behavior packs (including scripts using @minecraft/server and @minecraft/server-ui).

2. Attempt to join the world.

3. Observe the error message.

Expected Result:
The world should load normally with the custom behavior packs active.

Actual Result:
The game fails to load, showing a pack loading error and blocking entry into the world.

Notes:

• The Mining Simulator world uses several custom behavior packs with scripts And also has Beta Api Enabled.

• Restarting or redownloading the packs does not fix the problem.

Lastly Please fix this bug as soon as possible.. I do a technical side JavaScript programs in my world i don’t wanna lose my world T_T
