Hello, Unity: v.2020.3.18f1 Personal Visual Studio Community 2019: v.16.11.5. .NET Framework: v.4.8.04084 I came across a bug today where Visual Studio disconnects from Unity when working with an event in an animation. I added an animation and created an event within the animation (it was a read only animation if that is of any help). I left everything else untouched and did not hit save in the properties after adding the event. After I hit play in unity, Visual Studio auto-disconnected from Unity on loading any script (it first connected and then disconnected once loaded completely). Restarting VS/Unity and reboot did not help. After trying several other things, I deleted the animation and its seemingly broken event and reconnected visual studio under settings and now things work again. Not sure if that helps, but i felt reporting it might be better than not.
