Edit: This also works for the No Mans Land update, as it too, needs you to update the mod framework. You can join the darktide modding discord and look for a list of broken mods that you will need to remove or update as well, as quite a few broke with the update, or experiment on your own.
This video will help you fix crashing due to outdated mod framework as well as show some mods that at the time of this video coming out will have errors or also cause crashing, though its not likely to have all mods that may cause issues
