I'm getting the same thing when I try to upload a build to ASC. I've had bitcode disabled for a long time and have had no problem making builds as recently as last week. I can barely find any information on what to actually do to resolve this error. The only thing that came close was some Stack Overflow posts about using .NET Maui

@adamglo Did that manage to fix things for you? I'm sitting here waiting 3-4 minutes every time I make a minor text change and it's killing me.

Ugh. So the customer had spelled the app name wrong. Sorry to have wasted everyone's time.
