Mixamo addon not working on Blender 4.0

Could they please fix this, I was working on a project, and would really love to stick to Blender 4.0, its causing me a headache, i thought i could use, rigify, but mixamo's offers a faster workflow for me. Even when installing it takes longer and halts for some reason now, and i have to click to the side or resize the window to show the addon, when i proceed to activate it, the error pops up.

please @Adobe fix this.
