parameters.buildConfig is typically passed as lowercase (e.g., release), while the build/publish infrastructure uses the cased $(_BuildConfig) (e.g., Release) for artifacts/log/$(_BuildConfig). On macOS/Linux this would send MSBuild crash diagnostics to artifacts/log/release/..., which won’t be swept by the existing log-gathering step (and may create a parallel directory). Consider basing this path on $(_BuildConfig)/$(buildConfigUpper) instead, and ensure the target directory exists before the build so MSBuild can write the failure files.

Suggested change
value: $(Build.SourcesDirectory)/artifacts/log/${{ parameters.buildConfig }}/MsbuildDebugLogs
value: $(Build.SourcesDirectory)/artifacts/log/$(_BuildConfig)/MsbuildDebugLogs
