OK, based on some further testing and checking binlogs, we have confirmed it was the new linker step that was added in GA. This was disabled for the upcoming service release in #11096 as a result of #11069.

The solution for now is to use this in your csproj:

<AndroidLinkResources>false</AndroidLinkResources>

The next servicing release of .NET MAUI will have this disabled already.

Will this always need to be disabled? It makes the building process take 5x the time it used to.

This should fix it:

<AndroidLinkResources>false</AndroidLinkResources>
