Hi,
Not sure if this help anyone or not.
In my case it is because I updated the version. The old version was 1.0, but I upload a new build with version 1.0.1. It showing that version for a while and then disappeared.
Try upload build again, XCode archive success but it showing the same error, 1.0.1 showing in testflight for a while and then disappear.
Try change version to 1.0.0 also not working
It only working when I change version to 1.1 > archive and Distribute again.
