Then, a new empty scene is loaded with just a script that calls Application.Quit() on the Start method.
Remember to add the new scene to the āScene In Buildā list in the Build Settings.
Please file a bug report. There are many things that can cause this issue, we will need a reproduction project so we can identify what is causing it for you.
As you said there can be multiple ways to cause this issue, I donāt have much hope in truly making this issue go away. Unless Unity restructures the way it shuts down to make this impossible to happen. (Having the Rider IDE open can sometimes be an easy way to repro)
So thereās an easier way to deal with this:
In Windows 11, you can enable the āEnd Taskā option in the context menu when right clicking the Unity icon on the task bar. This saves you the trouble of opening the task manager to look for Unity.exe which can sometimes be buried under Unity Hub.
Yes I will try to reproduce it in a small project. It doesnāt happen in an empty Unity 6.34 project but it does for our game.
Also it doesnāt always happen. But when it does and it blocks / stops the internet from working I tried leaving the editor running for an hour to see what happens. It will slowly take up more and more memory until maxing out avaliable RAM. So it seems like some process is trying to run and maybe using up all the resources, bandwidth, etc, not sure. Just some observations - but will continue trying to reproduce it.
I downgraded to Unity 6.24 and it stops happening.
Seems to happen in 6.32, 6.33, 6.34 when I install this asset.
It happens cause it tries to fetch a version file from github and is unable to or something so it keeps retrying or uses up all the available network ports. I didnāt fully debug it but itās reproducible when installing this asset in 6.32+
When I downgraded back to 6.24 the asset doesnāt cause this issue. So I assume something must have changed in some of the unity updates to allow all the outbound ports to be used up. This also explains why existing tabs and network connections donāt get impacted, while new tabs and connections are unable to connect to the internet.
