Steps to reproduce:
1. Create new Unity project (e.g. 3D Universal)

2. Open the Search/Indexing Preferences page and enable "Index on editor startup" if it's not already enabled.

3. If indexing already happened, close Unity and delete the Library folder then reopen Unity.

4. When project is opened - open the Background Tasks window in the right down corner - the "Building Assets Search Indexing" process should be running (it starts immediately after project is opened and runs for around 30 sec, so be fast :) ). If it is finished - the crash will not happen. See screenshot in the pinned comment or the attached video "ReproSteps"

5.While the "Building Assets Search Indexing" is ongoing - open Standalone Profiler (Window > Analysis > Profiler (Standalone Process)) 

6. Observe the window

Actual results: Standalone Profiler window crash once opened (throws Bug Reporter). Note: Editor is not crashed - only Standalone Profiler window is crashed
Expected results: Standalone Profiler window doesn’t crash once opened
