App is not upgrading with Network Extension in iOS 13 in Test flight

Hi
We are building a VPN app (PacketTunnelProvider) and allowing users to install the app through test flight and app upgrade works seamlessly without VPN, but immediately after enabling the VPN, we are not able to get the app upgraded with the progress bar in test flight stuck at 90 percent and now app is not usable after that but VPN is still working.
We are not noticing the issue on ios 12.4.1 version but facing the issue on iOS 13 versions. 
On looking through console app during upgradation process we are noticing a below recurring log message.
Code Block
Error acquiring hold on plugins for <bundle_identifier>: Error Domain=PlugInKit Code=14 "plugins are busy" 
UserInfo={busyPlugInUUIDs({        
XPCExtensionBundleIdentifier = "<bundle_identifier>.tunnel";    
}), NSLocalizedDescription=plugins are busy}

Could someone please help us in resolving the issue.
The situation you are running into is a known bug. I am currently tracking several related bugs internally with similar steps to reproduce. If you have not already please file a bug report.
