Assertion failed: Can't add a new vertex field at this point: COLOR

Partner Rank: 2

Partner Team Reporting:  Shaliquinn's Schematics

Verification Build: 1.19.60

Summary:

Assertion error thrown when near content converted by Chunker.

Impact:

Prevents players from using converted content at all.

Repro Steps:

1. Download and install the world provided to Chris in our partner chat

2. Load world

3. If spawning outside of the converted area, approach the converted area.

Repro Rate: 3/3

Observed Results:

When player is within range (approximately 350 blocks) of Chunker converted content, an assertion error is thrown:

Assertion failed: Can't add a new vertex field at this point: COLOR Condition is false: false Function: Tessellator::_checkFieldSupport in D:\a_work\2\s\handheld\src-client\common\client\renderer\Tessellator.cpp @ 120

If ignored, the following assertion error is thrown:

Assertion failed: Mismatched fields
Condition is false: data.mColors.size() == data.getVertexCount()
Function: mce::MeshGenUtil::findVertexFormat in D:\a_work\1\s\handheld\src-deps\MinecraftRenderer\src\renderer\MeshGenUtil.cpp @ 141

This occurs whether spawning in the converted area or spawning outside of it and approaching it.

Expected Results:

The world should load with the player spawning near the center of the converted area without any assertion errors.
