Xcode 15.1: Crash When Opening Swift Files and Non-Zero Execution Error

I am encountering critical issues in Xcode 15.1 related to project merging, leading to a crash when attempting to open Swift files and persistent non-zero execution errors. This problem was not present in previous Xcode versions, specifically Xcode 13 in Ventura 13, and seems to be a regression in the latest release.
Thank you for your attention to this matter.
