Hello, we are having the same issue.
We went back using macos 14 and Xcode 16.2 to avoid the crash.

Hi @ijunaidm1 ,

Thanks for picking this up. Here's the workflow run I tried when the issue occurred:
task: Xcode@5

• We just checkout the code and run xcodebuild clean test

Hi @surendrapatel-rak , we're still looking into this issue, but the reproducing steps provided so far aren't entirely clear. Could you please help us by sharing the following details:

• A link to the last successful run
• A link to the most recent failed run
• Detailed steps to reproduce the issue, including the mandatory example project code and workflow (if the project is private)
• Without complete reproduce steps, it’s difficult for us to isolate and resolve the problem.

Thanks!

Hi @guillaumeramey ,
Thank you for the reply, Solution worked for me. For now we could downgrade until fix is not available.
