Happens always after a period of time (~half an hour) when switching from Visual Studio to Unity and hitting play. I have not experienced error to show up when using JetBrains Rider yet.

It happens sporadically in Unity 2017.1.0f3. I was left with the feeling that is caused in conjunction with VS 2017.

Same issue for me. Happens irregularly, but typically each 2-4 hour into my work. No data is saved on crash. Typically happens when pressing play but cannot confirm that for every case.
Unity version: 2017.1.0f3
OS: Windows 10, 64-bit.

Unity 2017.1.0f3 running on Win7 Pro 64 bit version and the error pops up about every hour. It makes development a little more stressful wondering what I'm going to loose and when.

2017.0.1f3 here. This is a brutal issue. Even though I'm paranoid and saving constantly, I'm still occasionally losing work. It's still early in this particular project, so I'm starting to consider maybe using a different engine.

This is happening here on my end as well, i might just have to go back to 5.6.0f3 as i was not getting this error there.
