The crash dump indicates it's a shell extension that's going wrong, and not Opus itself. If it only happens when you double-click videos, and/or enter folders containing videos, then I'd focus on video-related software. (If you're in Thumbnails or Tiles modes, or displaying thumbnails via another method -- e.g. hovering over the file before double-clicking, for long enough to trigger the infotip with a thumbnail --, or if you have the viewer pane open, then it could also be video codecs/splitters crashing.) The crash dumps show several shell extensions installed, but don't give a definite indication of which one is causing the problem. So the best thing to do is try disabling them all, and then re-enable a few at a time until the issue comes back. Repeating that process should quickly narrow it down to the problem component. Once you know the component causing the problem, check if there's an update for it. If there isn't, you can leave its shell extension disabled while still using whatever other functionality the program it came from provides, or uninstall it. Let the authors of it know there's a problem so they can fix it as well, and let us know so we can keep an eye on similar issues other people might have. (If a component causes enough problems without a fix, we can block Opus from loading it to save other people from the problem.)
