I'm running into the same issue (Xcode 26.0.1 on macOS 15.7.1). I've added a retry logic to my build script. It now just retries on error 65. Of course each failed attempt takes a minute or two. This is very frustrating. set +e while true; do xcrun xcodebuild archive (...) case $? in 0) break ;; 65) echo "Received Status 65. Probably asset compiler bug. Trying again!" ;; *) exit $? ;; esac done It usually works after 3-5 attempts. But that's ridiculous!

Will there be a release for macOS 15.7.1? According to uname -v the Kernel version was updated to 11417.140.69.701.11
