Refer this to enabled or disabled Test Visualizer that captures images
https://support.smartbear.com/viewarticle/89392/
TestComplete includes Test Visualizer that captures images of your tested application for each UI action performed during test recording and playback. These screenshots help you better understand the test flow and analyze the test run sessions. However, it takes additional time to capture images, which decreases the overall test execution speed. Moreover, captured images may occupy a lot of disk space, especially if you run large tests that include lots of UI actions or if Test Visualizer is configured to capture the entire desktop. So, disabling Test Visualizer may increase the speed of your tests and allows you to save the hard disk space.
^^^ as they have said, sounds like you need to sort your logging or make more space available on that machine.
In the crash report:
"Fault Module Name: aqReporter.dll"
I presume aqReporter.dll is the loggin component? Sounds like it.
