Blender 4.02/4.1 on Mac Internal Server Error 500 for Verge3D 4.5.1 and 4.6

Hello,

After installing Blender 4.1 earlier this week I installed Verge3D 4.6 on my Mac running MacOS 14.4.1 and now the application manager will not start. I get the following error: 500: Internal Server Error whether I use Chrome or Safari. Verge3D was working before the upgrades.

I tried downgrading to Blender 4.02 and Verge3D 4.5.1 and it gave me the same error. I tried clearing Chrome’s cache, no go.

Here is what I get from Blender’s console when I try to run the application manager:

Read blend: “/Volumes/Files/Blender/Web_Apps/swiss_army_knife_toby/swiss_army_knife_toby_v2.blend”

Any help to get Verge3D working again will be appreciated!

Thanks,
