My application is not shown in the testflight, but in xcode everything is successful

A few months ago I uploaded the latest version of my application with xcode 11, everything seems fine to me.

But when I updated the xcode, now the new versions that I want to distribute does not come out in the testfligh. (The version comes out for a few seconds on the web, in the testflight but not the package, then it is deleted).

When I give it to file in the xcode and the whole process, everything ends successfully. but it does not appear in the testflight to be able to distribute it.

I checked my emails in case something arrives, but nothing arrives. I do not know if it is because of xcode or another error in the code that cannot be loaded. Help
