that should take care of it. Not sure yet what changed about this line that it does not have an effect.

'export' is not recognized as an internal or external command,
operable program or batch file.
export XUNIT_HIDE_PASSING_OUTPUT_DIAGNOSTICS=1

Is TargetOS misdefined?

runtime/eng/testing/xunit/xunit.console.targets

Line 17 in 39a31f0

<SetScriptCommands Condition="'$(TargetOS)' != 'windows'" Include="export XUNIT_HIDE_PASSING_OUTPUT_DIAGNOSTICS=1" />

Yes, TargetOS=browser and that condition should be "'$(OS)' == 'Windows_NT'". However, that's not the reason for the failure.
