Hello Everyone,

Even I am getting the similar error. When I tried to add more than three sheets , .PBIX file is throwing this above error. 

Can someone help me in recovering my file?

Try restoring a previous version of your pbix file. At least you will beable to fix what was changed before the error.

Hi @aakgun,

I am unable to reproduce the issue when I test your scenario. Regarding to the above error message, there are some proposals for you troubleshooting it.

1. Make sure that you use the latest version of Power BI Desktop (2.36.4434.381).
2. Ensure that the PBIX file is not corrupted. You can try to copy & paste visuals using other PBIX files and check if the error still persists.

Also I will appreciate that if you can share me the PBIX file, I will test it in my Desktop, and please elaborate more details about that what type of visual you copy & paste and how you change data format.

Thanks,
Lydia Zhang

Hi Lydia,

I can send you the PBIX file, I have already done similar copy paste visuals in other PBIx files. You can find the the file here.

Hi @aakgun,

I am not able to view the PBIX file. Would you please share it using Onedrive?

Hi,

we have Excel data source and three report pages. We have copy and paste one visual from one page to another, as last remember and some small changes about field data format percentage.

nothing more unusual.

Thank you
