 ### Fixed
 
+- Fixed issue where `NetworkManager` was not cleaning itself up if an exception was thrown while starting. (#3864)
 - Fixed memory leak in `NetworkAnimator` on clients where `RpcTarget` groups were not being properly disposed due to incorrect type casting of `ProxyRpcTargetGroup` to `RpcTargetGroup`.
 - Fixed issue when using a client-server topology where a `NetworkList` with owner write permissions was resetting sent time and dirty flags after having been spawned on owning clients that were not the spawn authority. (#3850)
