The game will not startup and will leave this error message in the logs:

The crash does not happen on 1.4.9, but the problem is that I need to use version 1.4.10 since it's the only version on 1.19.2 compatible with L2 Hostility,

same old problem. ItemPhysics is not compatible with L2Complements. Their dev fixed it in 1.20, but they don't support 1.19 anymore
