How to reproduce:

1. Open the project “IN-95467_My project”
2. Open Window → Analysis → Profiler
3. Run the build: File → Build Profiles → tick Autoconnect Profiler
4. In Build Profiles click the Build button
5. Run the Build
6. In the Profiler make sure the record button is red (recording)
7. In the running Build click the button “InitiateTest”
8. As soon as the terrain is loaded in the Build click the record button
9. Observe the CPU usage in the Profiler

Expected result: No big CPU spike, Loading.AwakeFromLoad runs without locking the main Persistant Manager
Actual result: Big CPU spike and stalling main thread with Loading.AwakeFromLoad and Loading.LockPesistentManager

Note:

• In the 2022.3 stream the button in step “6.” “InitiateTest” has no visible text, clicking the white part still works
