Unhandled exception: listen failed: EINVAL (Invalid argument)

I was using it on Graphene OS as normally install it was working fine. but when I set it as pre-installed the following issue occurs when ever i am connecting/running the vpn service. Device information is also there.
Also note that i have set other apps as pre installed as the same way as this app, Other apps are working fine but only this app is causing the issue.

I have no idea what setting a pre-installed actually does but it looks like it messes with some integral part of the app related to the unix domain socket. I cannot really help with that.
