Downgrading to Beta 2 did not help for me. Running Sonoma 14.0 on a M1 Max w/ 64GB RAM. Here is the error message : Error: apple/apple/game-porting-toolkit-compiler 0.1 did not build Logs: /Users/user-name/Library/Logs/Homebrew/game-porting-toolkit-compiler/02.cmake.cc /Users/user-name/Library/Logs/Homebrew/game-porting-toolkit-compiler/00.options.out /Users/user-name/Library/Logs/Homebrew/game-porting-toolkit-compiler/clang-build /Users/user-name/Library/Logs/Homebrew/game-porting-toolkit-compiler/02.cmake /Users/user-name/Library/Logs/Homebrew/game-porting-toolkit-compiler/01.tar Do not report this issue to Homebrew/brew or Homebrew/homebrew-core!
