Steps to reproduce:
1. Create a new project or open an existing one
2. Open Standalone Profiler
3. Enable Deep Profile
4. Switch to Editor Profiling mode

Expected results: No errors or warnings in the console
Actual results: "Sending message header failed" warning spammed and then calling auto disconnect

Reproducible with: 2020.3.28f1, 2021.2.10f1, 2022.1.0b6, 2022.2.0a3
Cannot test with: 2019.4.35f1 (Standalone Profiler not yet available)

Notes:
- In 2022.2 it crashes the Standalone Profiler with the header warnings spammed in editor after enabling Deep Profile
- In 2021.2 and 2022.1 the Standalone Profiler console is spammed with "RefreshInternalV2 is called before InitialRefresh has been called and asset database isn't fully initialized." errors after enabling Deep Profile
- Reproducible on Windows, Mac (though Mac crashed 1/2 times, so might be inconsistent)
