Hi,
we are seeing this exact same issue with iOS 26.4.2 + the current iOS 26.5 beta version.
We can not update our App anymore having the VPN tunnel running!
Removing the VPN Profile instantly resolves the issue.(which isn't a solution)
installcoordinationd:
Failed to acquire termination assertion
RBSRequestErrorDomain Code=5 "Error acquiring hold on plugins"
PlugInKit Code=14 "plugins are busy"
busyPlugInUUIDs = ******.NetworkExtension
Same build is perfectly updating on e.g iOS 17.* or IOS 18.* devices.
