TestFlight build issue

I am trying to upload a build to appstore connect from xcode. I am successfully uploading the build to TestFlight app and the build is getting disappeared after few seconds. Please check the screenshots for the reference.

TestFlight app is not showing the build status after successful upload.

When i refresh TestFlight tab after few seconds, the build is getting disappered and showing No Builds in Builds menu.

I am facing this issue since 2 weeks. Please help me to resolve this issue..

Thanks in advance..
