Failed to decrypt credentials error

Dear All,


I have the following issue while trying to open Power BI Desktop:




Can anybody help me with it? The file that I'm trying to open has only Excel Workbooks as a Data Source.


Thank you, Eric. Going back to the March version solved my issue for now.

We are also seeing this issue company-wide and opened a support ticket with Microsoft.

It seems like the April 2021 update broke something.  I installed the March 2021 version and it works again.  See here:

I have the same issue. Suddenly, i cannot access to any files I have worked. I am using the free Power BI desktop. Is this the reaason? I need to upgrade to Pro to make it work?

No, I just cleared the Cache folder and it worked. It's better to uninstall & then re-install app after you clear the Cache

Can you specify which Cashe folder you cleared? Are you using April version?

I am getting the exact same error.  Worked Friday; not today.  I can’t even connect to a file stored locally.  If I go to File > Options and settings > Data source settings… it is all blank.  And each time I click on “Global permissions” the same error message pops up.  I'm not sure how to clear the credentials when it looks like there is nothing to clear.  Similar to OP, tried re-installing Power BI Desktop.  Any help would be greatly appreciated.

I cleared the Cache folder, and it worked!

@amitchandak  Thank you for your response. No, it is not saved with a password. And I think I'm using the latest version, cause I uninstalled and re-installed it again.
