This test is disabled. It is still failing even after the test got disabled.

I think this might be related to the test logic in xunit.Per your comment, the test was already disabled, so I doubt that the PR you merged had an effect. I created a new PR #124076 to probe disabling runtime async on Apple mobile since the failure is happening in System.Runtime.Tests.The crash dump for App terminated due to signal is uploaded in the artifacts as an .ips file and could be parsed using Xcode.

Also happened in #123601.
kotlarmilos commentedon Feb 6, 2026
Yes, the PR #124076 mitigates it.

There are number of tests disabled against this issue.
Remove ActiveIssue #124072 from RuntimeAsyncTests
