Recently, Forge keeps throwing an error for "unauthorized - api key does not have permissions write-assets. This recently started after I installed TheForge module and plugged an api key into it. I uninstalled the module, but it’s still happening, and now I can’t upload any new assets.
The Forge module is auto-pushed into your Worlds so you can access your Assets Library, there’s absolutely 0 need to install it.
That said, go to your Module Settings and DELETE the API Key. As the Account Holder you don’t need an API key, you being logged into Forge is your authorization to the Assets Library.
