Hi @mashrulhaque ,Apologies for the delay,
Please note that "NuGet.org depends on a partner service to validate packages and sometimes the package is flagged to pass the manual validation". However, as the package is stuck in validation for more than 1 week, We reached out to our internal team for further investigation on the issue.

We will keep you posted with updates accordingly.
