2. Make sure that the game version 1.21.132.01 is selected with the LeviLamina mod installed and activated.
3. Launch the game and connect to any server (an error was received when connecting to a server with a BDS).

Expected behavior

The game does not crash.

Screenshots

No response

Platform

Windows 11

Version

1.9.2

Additional context

No response

I couldn't reproduce it.

[LordBombardir]

I couldn't reproduce it.

The game crashes when trying to connect to the BDS server (I tried it on a server with EndStone). Connecting to a server with PMMP doesn't cause a crash. I also tried connecting to The Hive, and there was no crash.

[LordBombardir]

I also noticed on The Hive that mods for LL 1.9.4 were no longer automatically enabled. When I tried to enable them manually, I encountered a problem with the commands not registering. (UPD: Nvm. I changed the procedure for registering commands - it worked.)

[loud2pro]

I can reproduce this by joining cubecraft with LeviLamina loaded on the latest version (currently 1.9.5 as of writing this)

[Kashifro]

I encountered the same issue while testing a client-side mod. I was unable to connect to a Java–Bedrock crossplay server, but I was still able to join some regular Bedrock servers without any issues.

For me, the crash logs looked like:

[0xC0000005:ntstatus] The instruction at 0x%p referenced memory at 0x%p.
...
LeviLamina.dll -> ll::command::CommandHandle::registerOverload
LeviLamina.dll -> ll::command::OverloadData::setFactory
LeviLamina.dll -> ll::command::registerModManageCommand
LeviLamina.dll -> ll::command::RegisterBuiltinClientCommands::detour

I was able to avoid the crash and get the mod working by changing the config file located at:

levilauncher.exe\versions\1.21.132\mods\LeviLamina\config\Config.json

to:

{
    "version": 35,
    "language": "system",
    "modules": {
        "command": {
            "tpdimCommand": {
                "enabled": false,
                "permission": "GameDirectors"
            },
            "crashCommand": {
                "enabled": false,
                "permission": "GameDirectors"
            },
            "versionCommand": {
                "enabled": false,
                "permission": "GameDirectors"
            },
            "modManageCommand": {
                "enabled": false,
                "permission": "Admin"
            }
        },
        "crashLogger": {
            "enabled": true,
            "builtin": false,
            "uploadToSentry": true
        },
        "disableAutoCompactionLog": true,
        "vulnerabilityFixes": true
    },
    "targeted": {
        "showOutputWindow": false,
        "forceEnableCheatCommands": true,
        "playerInfo": {
            "alwaysLaunch": false
        }
    }
}

This worked for me
LeviLamina version 1.9.5
