Hey!
Do you have a way to repro this situation on my end? It's difficult to pinpoint exactly what's happening with the information provided, but here's a few things that you could try to check:
- Check if the query *ies) in the Power Query Editor refreshes and if you get a data preview.
- Check if the privacy levels of your queries might get in the way and perhaps disable the privacy levels on their machines.
- Do those machines have an older version of Power Query and you had a newer one? There might be compatibility issues if you created the query with a newer version, of perhaps there's a bug with the version that they have that was fixed in a later version (like the one you're using)
- Have you been able to pinpoint what are the differences between the environments so you can repro the errors on demand even on new machines?
