Enable build Addressable causes IOException, thus fail the build

When I enable building Addressable on UCB, I will always get an IOException stating some files have already existed (see the following screenshots).

It has been like this for the past year and only happens when they are Addressable set to local load/build path.


^ IOException


^ Addressable Enabled

Unity Version: 2020.3.38f1, same for UCB

Please, anyone? This has been failing me for over a year now. I have even asked on the forum multiple times before without getting any answer from the devs. It’s been extremely frustrating and I have wasted hundreds of hours trying to find a solution…

This would take some time for one of the developers to dig into. If you can open up a support ticket through the Unity Dashboard we can get someone assigned to look into the issue. Go to the dashboard → Cloud DevOps → Help & Support and then click on the File a Ticket button.
