Reproduction steps:
1. Open the project attached by the user
2. Open "SampleScene"
3. Enter Play mode repeatedly until it crashes

Reproducible with: 2019.3.0b11, 2020.1.0b5, 2020.2.0a5 (Entities 0.8.0, NetCode 0.1.0)
Didn't try to test with older versions than 2019.3.0b11 since it's the first version where NetCode is available

Stacktrace:

Notes:
- The project was made by following the steps here: https://docs.unity3d.com/Packages/com.unity.netcode@0.0/manual/getting-started.html
- The crash doesn't reproduce consistently
- Can't downsize the project much as any changes in packages or the project seem to decrease the likelihood for the crash to reproduce. Still looking for a more reliable repro
