This is still occurring in version 2021.3.10f1.

I have to echo the sentiments below. This is not on the user to work around. This should be a fix on the software side. The editor crashed during the first tutorial lesson I attempted and several times thereafter on various steps. I had to search online to finally determine the issue was related to my VPN service. Not a good first look for someone starting out with Unity.

Same is happening for Mullvad. Unity freezes so hard that system restart is needed. Version is 2021.3.8f.

Can this really be called a third party issue? None of my other applications crash just because I happen to be connected to my (Nord) VPN. I was lucky to come across a reddit post mentioning the VPN link to the crash, or this would have remained an infuriating mystery. I can't vote because you have shirked responsibility, but please consider this comment to be my vote and please reopen this issue or we will just have to report it again. Happening to me currently in Unity 2020.3.21f1.

Still crashed on Unity 2021.1.28f1 & NordVPN 6.40.5.0
Lost about 1h30 this morning trying to figure out what it was

Please unmark this issue as resolved, as it is not resolved at all and persists on 2020.3.0f1 and NordVPN 6.40.5.0

Before the main part of my comment, I will add that I'm experiencing this issue with Rider, where the report itself suggests it's not reproducible with Rider.

This is categorically not resolved. While the NordVPN/SurfShark clients are clearly doing something that causes Unity to crash, the fact that I can find absolutely no other piece of software affects in the same way suggests that Unity is also doing something weird to trigger this issue.

Please fix this, Unity. Until you do, I physically can't use your products.

I also have exactly this problem. Everything works fine when NordVPN is switched off, but will crash after about 20 seconds when NordVPN is connected to a VPN.

I have over 20 years of s/ware development experience with C++, objective-c, python and .net / C# - and I don't agree at all that the customer should "work around" this problem.

It feels like there is some component in the background that is trying to "call home" or do some network access which is - for whatever reason - failing; and that the Unity code responsible doesn't catch or handle any kind of networking error. Now, I can't confirm this as I don't have the code - just speculation based on my years of experience in the field.

Secondly; NordVPN has a way to ignore certain apps - but I've read others have tried this, and it doesn't help - presumably because there is a spawned process with a different name from the main Unity program that is causing the problem.

Please correct the unity code - users should not have to work around what is clearly not a Windows or NordVPN issue.

I don't agree this is "fixed" or a third party issue (why can't I vote for this). Yes it's interaction with a VPN but however Unity is talking to the mothership is causing a hard crash.

For me just disconnecting the VPN and launching the editor works. I've looked through the "workaround" but that involves a complicated setup (IKEv2/IPSec) or another tool to install. I would just like Unity to not crash when I'm connected to NordVPN. Not sure why this is so hard.

Also able to reproduce this with 2019.4. Connect to VPN, launch Unity, wait 30 seconds, crash. Happens every time while connected. Disconnect and everything works fine.

I have this problem too. I went into NordVPNs split tunneling settings and disabled it for Unity Editor and Unity Hub, but it still crashes if NordVPN is connected at all.

I agree with Wenceslao, it doesn't make much sense that Unity should care what VPN or VPN protocol I'm using. Would very much appreciate a real fix for this one.
