Crash on "PiXYZ::Polygonal::QuadricEdgeHeap::popEåçdges" and multiple Bug Reporters open when clicking "A task is running..." during Decimate task

Steps to reproduce:

1. Create a new Unity project using Industry Fundamentals Template
2. Install the Asset Transformer Toolkit package
3. In the Scene view overlay, click "Import Model" and select "moto.SLDASM" 
4. Select it in the Project window and click Import
5. Drag the newly created prefab into the Hierarchy and select it
6. In the Asset Transformer Toolbox select the "Decimate" option
7. Click "Run"
8. While it is running, click on the "A task is running..." button
9. Observe the crash

Actual results: Project crashes and more than one Bug Reporter opens

Expected results: No crash

Reproducible with versions: 3.3.0 (6000.4.4f1, 6000.5.0b4) 
Couldn't test: 3.2.2 (6000.4.4f1, 6000.5.0b4)(Object.GetInstanceID() errors)

Notes:

• It seems that the longer the task was running, the more bug reporters open. On some instances 3-8 new Bug Reporter windows opened
