Hello @joshua _kushner
There is no official migration tool for wocommerce to magento2. I think, you have used any third parties custom module, might be cart2cart migration tool.
As per error screenshot, missed-up the relation of eav_attribute_group table. In magento2, added new field as attribute_group_code. Some time, these values not populating proper when using the migration tool.
If my answer is useful, please Accept as Solution & give Kudos.
Thanks!!
