Android build fails : RetargetAssets task files with System.ArgumentOutOfRangeException

[baskren]

When building the Android version of my Uno app, my build is failing during the RetargetAssets task (excerpt of the diagnostic build logs for this task are in the collapsable section at the bottom).

Looking at the logs and the corresponding source code, it's not clear to me what file is causing the issue. The last file that is retargeting:

 Retargeting generic '/Users/ben/.nuget/packages/p42.uno.controls/4.9.17/contentFiles/any/net7.0-android33.0/Assets/Sounds/Warning.mp3' to 'Android/Assets/eContainment4_Views/Assets/Sounds/Warning.mp3'. 

is also retargeted earlier in the process multiple time without incident (as are other files). Any suggestions on where I should be looking next?

Thanks for your consideration!
