Modding

Then I don't know how to help, the only thing I noticed is that the last parameters in your geom file are not quite correct (I compared it with what the editor gave me after exporting). In general, here is the model and geom from the editor.
And I extracted the skeleton from the game, but it doesn't matter whether it's 1 MB or 2, I always get this error:

How did you extract the skeleton?
In geom, it is indeed different; this is a side effect of Archangel. It had to be done this way; Zakhar does it the same way, otherwise, the game wouldn't recognize the meshes. There is no such thing when exporting from *.mb; the editor will generate the mesh numbers and their names itself.
The red text indicates materials, meaning that the textures are missing; this is a minor issue. I can try exporting it myself and record a video showing what I did. If successful, I will show the result. This is if I have time because I am leaving home and will only return to my computer in a month or a month and a half.
