Re: Bug in Desktop, Version: 2.79.5768.721 64-bit (mars 2020) - Error when "Apply query changes

I can confirm this is the case.  Enhanced metadata not enabled, but deleting a folder resulted in the failure to occur.

Re: Bug in Desktop, Version: 2.79.5768.721 64-bit (mars 2020) - Error when "Apply query changes

This issue is still present in May issue of PowerBI Desktop, and I don't have any folders in Power Query.

But the bug is Power Query related since if you try to delete 1 column from any of the tables 

in the Power Query the error will appear once you try to apply the changes.

 

The only workaround for me is deleting in the model view, and I am not happy about it.

Same issue here, since April release getting below error and not able to solve it.

 

An unexpected error occurred (file 'tmsavepointvalidation.cpp', line 408, function 'TMSavePoint::VerifyProxyCreationAllowed')
