Importing MSFS .gltf fails

[jonstanley]

Current Behavior

Installed "glTF-Blender-IO-MSFS" plugin, then "msfs-blender-tools", and running Blender with Administrator privileges to install the depenedencies, finished with a full restart, on importing a compiled MSFS .gltf, the following error occurs.

Can't get old Blender 2.9x to work with the previous "msfs2blender2msfs" plugin either, but can't report bugs on that one as the repo has be archived and not reports are allowed anymore. Just want something to work...

Expected Behavior

It should just work... plus no way to verify if "pillow" dependency was ever actually installed...

Steps To Reproduce

1. On Windows 11, Blender 3.1.2 clean install
2. Install glTF-Blender-IO-MSFS, activate and restart Blender with admin privs
3. Install msfs-blender-tools, activate, install dependencies, restart Blender
4. Import MSFS .gltf model, all extensions to importer is enabled
5. Import fails with above message

Environment

- OS: Windows 11
- Blender: 3.1.2
- msfs-blender-tools: 0.0.1

Anything else?
