Power BI Report Builder not opening



Power BI Report Builder has stopped working. The loading image just flashes and nothing happens.


2 different errors appear in Event Viewer, one from .NET Framework and another from KERNELBASE.dll. These errors are in Finnish, sorry for that.






What I've tried so far:

  • Reinstall the Power BI Report Builder multiple times.
  • Fix it with it's own repair tool.
  • Fix .NET Framework with repair tool.
  • Delete the user.config from C:\Users\<USERNAME>\AppData\Local\Microsoft\Power BI Report Builder\15.7
  • All Windows updates are up to date


What to do next? I have this same issue with my desktop and laptop.
