Please describe this in more detail.

Blender 4.5.2 has been released and fixes the issue.

None of that sounds related to Blender at all, sorry.

You didn't describe the problem. Is it that no file is exported? That it exports with the wrong filename? That the content of the file isn't what you expected?

You can fix the misnamed export filename by downgrading to Blender 4.4.

This will be fixed in the next version of Blender.

You didn't really answer any of my questions, but I've found out for myself that this broke in Blender 4.5. I submitted a bug report here.[projects.blender.org]

For now please downgrade to Blender 4.4.

With which version of Blender, which version of the Blender Source Tools, and which .blend file?

There is a corrupt Unicode character in your SMD file. There's nothing the Blender Source Tools can do about this. The data isn't there.

Sounds like a corrupt Blender installation. The typing module should be there.

This was fixed in 3.4.1. You need to update Blender, then update the addon.
