Is this a Murder Hornet?
First, how shocking to find something that wasn't crawlfish with you crawlfish. It's not easy to identify at this stage in the game. It's unlikely to be the Asian Giant Hornet for a few reasons. First, it has not been spotted outside of the northwest corner of Washington. Second, there are many other insects that are big and confused with it (see the link below). Keep your eye's peeled (and use the images in the guide below to help). If you think you see an Asian Giant Hornet, you can submit the image to Oregon Department of Agriculture.
