Hi @Anonymous,

Please try below steps:

With PBI Desktop closed, open up File Explorer and go to %LocalAppData%\Microsoft\Power BI Desktop\

Delete the Cache folder.

Start PBI Desktop and attempt to open reports again.

Best Regards,

Which encryption are you using? For testing purposes can you try a non-encrypted connection to your SQL server?
