Unfortunately, Indexer and the Light Info share both view layers and bake materials and this results in the color generated by the indexer nodes to be baked onto Light Info as a color.

The easiest solution is to not bake Indexer and Light Info at the same time if you will need color Information.

The name and suffix combination sometimes makes it difficult for Texture Pabrika to match object names.

The simplest solution is to change the name for both source and target object.

If that's not doable, changing suffixes might also solve the problem but may require a little more work.

Blender cache sometimes store collection properties which affect how Texture Pabrika evaluates source and target collections.

Try to save and restart Blender.

Texture Pabrika is designed to recover from an interruption. So you can immediately try and Bake Data Maps again once you've addressed whatever it was that caused the interruption. But, in case there has been some damage to the data that's been generated and Bake Data Maps is not pushing through, here's a few things you can try:

1. The easiest way to fix it would be take note of what interrupted the bake, re-open a previously saved file and then address whatever it was that caused the issue.

2. In case, that is not an option, you can go through each material in your blend file, delete any secondary material output which you should find a few units to the top of the node tree, and all nodes connected to it. You'll also need to manually remove all View Layers which should have the prefix "Texpab" attached to its name.

If you had Bake Target set to "Collection":
If (though the very rarely) an empty image is causing an issue, you can remove empty images generated by the Map Baker by going to your outliner, switching your outliner's display mode to "blender file" and under the "images" folder, delete empty images.

You can also make sure you're file is clean again by heading over to the node view of your target material and check if any image node has been generated. You may delete these nodes without worry since Texture Pabrika will just create new ones if it's unable to find them.

If you had Bake Target set to "Color Attribute":
You'll have to go through each mesh object in your source collection and delete color attributes generated by Map Baker Utility.
