Summary
So many people get Error Code IS-0009 when trying to install or update an existing Unreal Engine plugin.
This has been plaguing hundreds of developers for so long now. This should be Epics number one priority to fix this.
What type of bug are you experiencing?
Plugins
Steps to Reproduce
I am not 100% sure why this happens. It seems like it can randomly happen to any user. It is definitely account-based and not product-based. Though it seems to only happen to products that already existed on the Unreal Engine Marketplace. I added much more information, thoughts and potential reasons in the countelss support requests I already sent.
Expected Result
Plugins installs/updates normally.
Observed Result
Install failed. Error Code: IS-0009 happens instantly without it even trying to install it.
Platform
All
Operating System
Windows 11
