Solved by @t-bltg in this thread:
On your screenshots, your artifacts folder is empty, this explain the error loading the dll s.
Delete it, and then run pkg> instantiate : it should download the artifacts and you should see bin and / or lib with dll s in it.
Try e40afe22fcfc9fe1caea4af17a4016e7ef36cd66 first, then artifacts if that still does not work.
