February 20th, I was working on Power BI Desktop and it goes well and then suddenly I got this error when I tried to refresh the data:
An error happened while reading data from the provider: 'Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'
I also got the same error when I tried to get/transform the data in power query. It still working well in Power BI Service though. The source are from PostgreSQL database. anyone know how to fix this?

Hello,
Your answer is not acceptable, I still have the same error with PowerBI desktop Version: 2.126.1261.0 64-bit (February 2024)
Please tell me how to downgrade to the previous version of PowerBi Desktop, which did not contain this bug.
Thank you for your prompt feedback
