Hi @Anonymous , 

This error only occur when you modify power query? If you re-install the powerbi desktop to newest version , and run it , will it work well? By the way, I think you also could post this problem in Issues  or open a support ticket for this problem

I am currently running into the same issue; when i try to load changes from Power Query Editor, I am getting the error "the given key was not present in the dictionary". The data source has not changed, but i have cleared and reset the credentials. I have also updated the Desktop App to the October 2021 version, but none of this has helped the error. All queries are loading fine within Query Editor. Any suggestions?
