Duplicating query leads to "Item has already been added" error and corrupted file

[scott_s]

I have a recurring issue across multiple PBIX files and multiple machines over last few weeks.  It usually surfaces as I am in Power Query and right click and select Duplicate on an existing query.  I get the error message

"

Something went wrong

Item has already been added.  Key in dictionary: '[existing query name]' Key being added '[existing query name]'

"

I can add a blank query at this point and copy/paste code in but the damage to the file is done.   After i save, the next time I try to open the file I will get this error:

"

Unable to open document

'C:\[path to file]' can't be opened.  Either fthe file is encrypted or corrupted.

"

I thought this issue might have to do with my recent decision to have my pbix files in a OneDrive folder for version history.  One computer has done better now that I develop locally.  But today I got the message on another machine after I moved the file out of OneDrive to a non-synced local folder.

My only recourse is to go back to a previously saved version and redo my transformation work.   Since I'm not on OneDrive I have to keep doing File - Save As to new filename to prevent loss of much work next time this happens.

This is on Version: 2.108.997.0 64-bit (August 2022)   

Any ideas how to address?  This is a serious productivity issue.

I am getting the issue where the PowerBI file keeps corrupting after the above error message appears.

Is this a PowerBI issue? I am not doing anything different to the queries and it seems random when it chooses to corrupt.

[scott_s]

It seems random for me but once it starts happening, and I revert to old file, it is more likely to happen again. 

For now I am trying to side-step the issue by just creating blank queries and using code in advanced editor to duplicate or reference the query I want to build on.  I just started this today so I don't know if this will work long term or some other function will cause the same issue.

[katiestockford]

It appears to be a large query I have that causes it to break but it doesn't have anything wrong with the query itself so is very odd. Let me know if that solution works.

[katiestockford]

Have you had any success yet Scott?

[scott_s · Accepted solution]

Now, every time I need to duplicate or reference an existing query I take a different approach than using the context menu.  I just creating blank queries and write or copy the M code in advanced editor to duplicate or reference the query I want to build on.  I have done this about 10 times over last few days and haven't had any further issues.

This worked great, thank you!

[scott_s]

Thanks.   No windows updates are pending.  On my personal PC I did reinstall Power BI a few weeks back when this happened.  For a couple hours I was able to work but the issue eventually re-occurred.  On my work computer I don't have permission to reinstall so I can't try that but my experience on my personal PC leads me to believe reinstalling isn't a solution.

@scott_s , Make sure no windows update is pending. Install update. reinstall power Bi and try.

If needed revert to Jul 2022 and check https://docs.microsoft.com/en-us/power-bi/desktop-latest-update-archive
