Host Test failures in rolling CI

[jakobbotsch]

In the latest rolling runtime pipeline run, two "Installer Build and Test" jobs failed. win-x86 timed out and linux-x64 segfaulted.
Job: https://dev.azure.com/dnceng/public/_build/results?buildId=1760633&view=results
win-x86 log: https://dev.azure.com/dnceng/9ee6d478-d288-47f7-aacc-f6e6d082ae6d/_apis/build/builds/1760633/logs/2460
linux-x64 log: https://dev.azure.com/dnceng/9ee6d478-d288-47f7-aacc-f6e6d082ae6d/_apis/build/builds/1760633/logs/1970

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

I've seen similar hangs in both #69120 and #69117 so am marking this blocking.

@NikolaMilosavljevic do you know of any installer related changes that could have caused this?

There were no recent changes in installer build.

[NikolaMilosavljevic]

Tests are likely related to dotnet host - we don't do installer testing in this job.

This seems to have cleared up so will close it.

Not quite, looks like this is still happening, e.g. segfault in https://dnceng.visualstudio.com/public/_build/results?buildId=1764534&view=results.
