System Information
Operating system: Windows-10-10.0.17763-SP0 64 Bits
Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.66

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash: 77d23b0bd7
Worked: (optional)

Short description of error
I'm not sure why I'm having this problem but seems like impossible to me to export any glTF file. I tried Binary, Embedded and Separate, with different setting and everyone failed with the default cube.

Exact steps for others to reproduce the error
Just open default blender and: File -> Export -> glTF 2.0 -> Export glTF 2.0

I tried in different blender versions (2.81, 2.82, 2.83) and always have the same problem. I'll past bellow the long error message I received:

(Update)

I did some investigation around and found out the problem was with the Python IDE installed with the NumPy package. Don't know and don't understand why but when you install the package in Thonny, the software creates this folder in this location:

C:\Users\Samuel\AppData\Roaming\Python\Python37\site-packages\numpy

And Blender start failing to export glTF. The problem was quite difficult to track because even uninstalling Thonny, this folder remains (even utilizing the Revo Uninstall to track missing files from regular uninstall).

So don't know if it is a Thonny problem (creating folders in the wrong place), or Blender problem (accepting that folder as "original" NumPy), but I can work around the problem just temporarily renaming that folder, and naming back everytime I want to use Thonny again. it's a dirty trick but works.

Even though the problem is not in the Blender side, it's here documented to anybody else that can face this.

This error can happen when using 32-bit Python modules in a 64-bit Blender. The default Windows download for Python is 32-bit.

It should not be looking outisde the blender folder for addons ever since 7c2f0074f3 can you still reproduce this on the latest buildbot ?

Unfortunately the Thonny IDE doesn't allow to choose which Python to Install. I don't have Python installed manually anymore and didn't have this problem with Python 3.7 64 bit when I did. And I did another workaround using Thonny's feature virtual environment (I know it's Python feature, but the IDE allow to manage it).
I tried the "latest buildbot" (blender-2.83-d0c159ae9745-windows64) and the problem persist.

When you start blender with the blender_debug_log.cmd batch file located in the blender folder, does it work?
