Still an issue. PR that potentially fixes this issue #19415. Also this issue is probably a duplicate of #15020

Still an issue and we hope this can get fixed too. Our pipelines intermittently fail while this task is trying to download dotnet 6, while build agents already have dotnet 6. This task needs and if else condition to check the local pre-installed version and use them instead of trying to download and fail.
