Hi, I'm facing similar, if not the exact same issue with my app. In my case it seems to happen as soon as I try to add the keychain sharing entitlement to the project. I get a successful build but a crash on launch. This only happens when trying to build and run as a catalyst app for Mac. Building and running for iOS works. Also my teammates with Intel based Macs are unaffected and able to build/run for Catalyst. To try and isolate things I've created a brand new test app. Environment: MacBook Pro M1 Max macOS 12.5 Xcode 13.4.1 Apple developer member and team Project Setup: Brand new project (File > New > Project > App) Team set to my company, signing cert set to me Automatically manage signing checked (Xcode managed profile) Mac Catalyst Checked (Target > General > Mac Catalyst Checked > Scale Interface to Match iPad) Build Target > My Mac (Catalyst) If I build and run from Xcode at this point everything works fine- the app builds and launches as a catalyst app on my Mac. Then I try and add the keychain sharing entitlement: Target > Signing & Capabilities > Add Keychain Sharing > Add Keychain Groups > set to the bundle identifier At this point if I try and build & run the app for catalyst (Target > My Mac (Catalyst)) it builds properly but fails to launch. I get the "Build Successful" message then a dialog that says " could not launch, the launcher has returned an error" (see the logs below). Interestingly, if I try and run for Rosetta (Target > My Mac (Rosetta)) I get the same failure to run, but it also crashes and throws a log into the console that looks very similar to the one above- specifically the code sign error and the x86-64 reference which is confusing as I'm on an M1 Mac. Any insight into this would be helpful as I'm not familiar with building Mac or catalyst apps. My experience thus far has been iOS only. Launch details and crash logs below.
