Clicking and holding anywhere on the editor outside the viewport when PIE causes a crash. The AudioRendering thread throws the following assert: Assertion failed: FreeClipIndex < PlayingClipsPool_AudioRenderThread.Num() TimeSynthComponent.cpp [Line: 774]
Tested in 4.23 (CL - 8386587), 4.24 (CL - 9526430)
1. Download the attached project
2. PIE
3. Click and hold anywhere outside of the viewport for 15-20 seconds
4. Resume focus to the viewport
Expected: The TimeSynth interval noises would repeat as usual
Result: The editor crashes
