I managed to fix this with these:
Installed the latest Swift package from apple: https://download.swift.org/development/xcode/swift-DEVELOPMENT-SNAPSHOT-2021-12-06-a/swift-DEVELOPMENT-SNAPSHOT-2021-12-06-a-osx.pkg
Installed the latest Swift Debugging symbols: https://download.swift.org/development/xcode/swift-DEVELOPMENT-SNAPSHOT-2021-12-06-a/swift-DEVELOPMENT-SNAPSHOT-2021-12-06-a-osx-symbols.pkg
Unchecked the "Make this app available" Apple Silicon Mac Availability in Pricing and Availability from AppStore
Added the libswift_Concurrency.tbd in Link Binary with Libraries from Build Phases and set as optional
