Build error leg or test failing: maccatalyst-arm64 Release AllSubsets_CoreCLR_RuntimeTests - CoreCLR runtime test work items (CoreMangLib, GC, jit64_3, Loader, Methodical_, Regression_) hang and are killed at the 3-hour Helix timeout (exit code 70)

Error Details
On runtime-extra-platforms (definition 154, required gate), every CoreCLR runtime-test work item on the maccatalyst-arm64 Release AllSubsets_CoreCLR_RuntimeTests leg hangs and is force-killed when the Helix work item reaches its 3-hour (10800 second) execution limit, reporting exit code 70. The same leg fails in this manner across multiple consecutive builds (e.g. 1567845, 1569716, source 1574051, follow-up 1574376), taking down CoreMangLib, GC, jit64_3, Loader, Methodical_d1/do/ro, Regression_7 and other work items in the leg.
