Issue #20631 has been updated by hsbt (Hiroshi SHIBATA). Status changed from Assigned to Closed macOS 26 beta and Xcode 26 beta is working fine with this issue. And the current macOS 15 on GitHub Actions is also working fine.

We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug. => 82573
