Scene Graph - Deeply nested entities seem to cause network error (primitive project can't launch)

Summary

While trying to reproduce a different issue, I run into a situation where a certain entity setup will cause the project fail to connect the client.

What Type of Bug are you experiencing?

Stability

Steps to Reproduce

Start the project vz_anomaly_4 (see code below). As of v35.00 the connection error happens every time. Sometimes the clients manages to connect, but the placed mesh entities or devices are not visible, the character is frozen until it errors out. Other times it just fails to connect entirely.

Expected Result

It should not fail to connect just because of some deeply nested entities with some long names.

Observed Result

Here are some example error logs:
