Error: A module named 'AtScale' hasn't been loaded

[lakesidecoder]

Hi,

I got this today when I tried to reopen a pbix file:

A module named 'AtScale' hasn't been loaded.

Today I downloaded the latest Power BI Desktop (Version: 2.66.5376.2521 64-bit (February, 2019)), and created this report using that version. I reopened the solution and get the above error. I have included the trace.

thanks for the help!
