We have noticed that in our CodeQL github action the autobuild fails a little less than 10% of the time.

When it succeeds the dotnet build --no-incremental /p:UseSharedCompilation=false completes without error, but when it fails the logs show a successful build but there is a non 0 exit code.
The fallback to MSBuild doesn't work for our project so the autobuild eventually fails.

So far the job has always succeeded when we re-run it.

Here is one example of the failure in our project:
