Error: Attribute has already been defined (APT0000)

At work, I switched branches and now I can't build any branch due to:

error: Attribute "text" has already been defined (APT0000) Resources/values/attrs.xml
error: Attribute "closeIcon" has already been defined (APT0000) Resources/values/attrs.xml
error: Attribute "text" has already been defined (APT0000) Resources/values/attrs.xml

The other seven developers don't have this issue.

I've done the following:

1. Deleted obj/Debug folder to clear out resource cache files and rebuilt
2. Removed all packages and deleted them and rebuilt
3. Deleted Visual Studio Community for Mac and reinstalled
4. Deleted the repository and cloned it again and rebuilt

Anyone else have something to try? I've run out of ideas.
