XCode 15.3 Crashing on Sonoma during app verification

Running Sonoma 14.4.1 and XCode 15.3 I'm unable to verify an app update. This app runs fine under Sonoma and the project has been verified many times before for earlier systems, but the new XCode crashes every time during the verification step. Of course this is stopping any further app updates. Is this known to anyone else? I've submitted the crash reports.
