When I go to File>External Data>Unpack resources it says "No packed files to unpack," so the textures are definitely fine. I also tried the dev build to combine the textures but I'm getting the exact same results

Rename your materials so that they don't start with material_atlas_, that should fix the Python error.

In particular, it's probably the material_atlas_low and material_atlas_hi, since material combiner is expecting their names to be of the format material_atlas_<unique_number>_<layer_number>. Due to them only having two _ in them, the code that tries to get the <unique number> instead gets atlas, which it tries to convert into an integer and fails with this error.
