You installed a version for 1.12, not 1.12.2.

Use a newer version of Forge, for 1.12.2.

Update your Forge version.

You aren't actually running the latest Forge: [18:02:43] [Server thread/INFO] [FML]: MinecraftForge v14.23.3.2655 Initialized

Alternate download links are provided, pull up the full version list and hover over the i next to the regular download link.

Look up how to change environment variables and delete the _JAVA_OPTIONS variable if it exists.

Forge deliberately does not split client -> server packets, only server -> client.

You ran out of memory. See: Picked up _JAVA_OPTIONS: -Xmx512M Look up how to change environment variables and remove _JAVA_OPTIONS.

No, it's actually a problem with some mod misusing entity data parameters. See https://github.com/MinecraftForge/MinecraftForge/pull/5129.

isAirborne is also a bad name: https://github.com/ModCoderPack/MCPBot-Issues/issues/605

Update Forge.

You should be providing your own teleporter implementation.

Neither water nor lava have a block model.

PathNodeType being an enum was discussed in https://github.com/MinecraftForge/MinecraftForge/pull/4598.

Try without the coremods listed.

See the existing thread.

Update Forge (and as you're using Optifine, that too).

Some mod is mishandling mob spawn entries (see https://github.com/MinecraftForge/MinecraftForge/issues/4950).

Known issue: https://github.com/MinecraftForge/MinecraftForge/issues/5114

You ran out of memory, you need to allocate more to the game. You're using the 32-bit version of Java, you should use the 64-bit version if possible.

While this may not be the direct cause of your issue here, that looks like a Java 9+ installation. You'll need Java 8 for Forge anyway, so you should try using Java 8 to start with.

The latest version of Forge is not being used there - you may need to check your launcher configuration.
