I just experienced this same issue on commerce_product's trying to filter by IS NULL for a specific relationship field to a commerce product. @cracu #3 code resolved the issue for me... But seems like that is the wrong long term solution. I have found multiple links that relate to this behavior over the past few years some of them are fixed. But appears it may be creeping back in? I am using latest Drupal 10.
