Randomly closing/crashing beta v0.93

No it's all the logging there is… What kind of camera is it?

Just wanted to provide an update on some of my troubleshooting efforts.

- The problem doesn't appear to be related to specific cameras.  I recently got some IDS and Basler cameras.  I experienced same random crashing and closing with IDS and Basler as well. 
- USB connections are clean and I was getting over 400MB/s with no drops.   
- I experienced the same issue even when running a Replay observer instance.  The instance just went away on its own.
- I re-installed Kinovea several times and also moved the program and capture folders to a SSD drive different from the Windows OS SSD drive to avoid any contention with Windows.

At this point, I'm at my wits end as to how to further troubleshoot this issue.  Welcome any suggestions.  Thanks!
I saw several unhandled crashes.  They happened during my testing, but I don't know when those occurred and what I was doing exactly. (Could be just an artifact the Replay instance errored out as the capture instance crashed.)  Here are some of unhandled crash files.

That doesn't sound good. However, I have version 0.9.3 running since release and never have had a crash. My default setup is having 6 Kinovea open at the same time without any problem.

To narrow the problem some infos would be interesting:

Are any other programs also crashing
Do the camera-drivers, if are installed, have the right version that is compatible with Kinovea 0.9.3. There are a lot of error messages related to the IDS-camera. IDS-software suite Version 4.93 will work. If you have the Basler pylon software installed, be sure to have 6.0 (not 6.1 !)

Try to deactivate all virus programs. To be save, you could disconnect the internet during testing.

However, what I have personally seen is, that once this type of error occurs, it definitively is time to reinstall Windows from scratch. Expecially if the windows version is updated from an older version (i.e. Windows 8), I have found similar problems. Another reason I have seen are some "tools" - installation (these nice small programs we all like ) that replace important Windows-DLLs.
Since longer time, I always reinstall the system on a clean partition if windows shows a strange behavior.

Futhermore, if the computer is running for some years, remove and reassemble the memory-chips after running a memory-checking program to secure that the chips are in good conditions. Also disconnect and reconnect the graphics card to the motherboard slot.
Good luck

Just wanted to provide a final update on this.  After several weeks of troubleshooting, I was to able to trace down the root cause. 
I used to have a USB video capture device connected to the PC.   I no longer use that device but the software was still installed.  It showed up as a camera source in Kinovea even though the device was no longer connected.  For some reason, one of the DLLs caused Kinovea to crash or close randomly.  After I uninstalled the capture device software, Kinovea works perfectly now.

The video capture device is called Cloner Box Pro https://www.cloner-alliance.com/cloneralliance-box-pro/   
The software it comes with is called Cloner Helper Pro https://www.cloner-alliance.com/hdml-cloner-pro-helper/
I don't know if you can install the software as it checks for the device and serial number when it runs.

The error message I got from Windows Log Viewer was:
