Item texture not importing into Win10 edition

We’ve been using the tynker item texture creator for a few days but today when we create new ones they won’t import - we just get a message saying failed and no info when you look in the logs? Any advice?

When starting a project in the Tynker Resource Editor for Minecraft, please make sure that the right version is selected - Minecraft Java or Minecraft Windows 10 based on your Minecraft version. If you’ve made sure you’ve chosen the correct version in the tool, and still have issues importing please reach out to support@tynker.com
