You could return Mixamo Fuse with the name Adobe Mixamo Fuse 2024

Hello, Fuse was on Steam

By @Franc34

Fuse is still on Steam

link = https://store.steampowered.com/app/257400/Fuse/

 I can't upload human models to Mixamo

By @Franc34

why not, its working at my end

to use Steam you need at least a Windows 10 system because they dropped support for old OS... if you want it to run on a different OS then the Steam forum has people talking about how to hack the app [results very]

if Adobe continued to use Mixamo Fuse I would create a 100% original work called Adobe Mixamo Fuse 2024, it is the same program but with new parts for your character and even upload it Mixamo's platform,

Adobe grabbed the Fuse because they wanted the staff and mixamo [the web site] is still online for uploading of models but Adobe has zero interest in 3D because its really a Windows only club
