[!] [!] Xcodeproj doesn't know about the following attributes {"preferredProjectObjectVersion"=>"77"} for the 'PBXProject' isa.
If this attribute was generated by Xcode please file an issue: https://github.com/CocoaPods/Xcodeproj/issues/new

Start by reproducing pod install with the reported CocoaPods 1.15.2, Ruby 3.3.4, macOS 15.4.1, and Xcode 16.3 versions. Read xcodeproj/project.rb around initialize_from_file and CocoaPods' installer/analyzer.rb integration path, then compare the related Xcode 16 issues. Done means projects using object version 77 and preferredProjectObjectVersion can be processed without the reported RuntimeError.
