Power BI Report Builder not opening

[TomiKasurinen]

Hello,

Power BI Report Builder has stopped working. The loading image just flashes and nothing happens. Running Windows 11 Pro, this issue has occured at least for this whole current year.

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.

Hi @TomiKasurinen ,

I suggest you collect process monitor trace to see if any information meaningful can be found.

What should I be looking for there? When I try to open the PBI Report Builder a bit over 36 thousand rows appears to that Process Monitor.

Hi @TomiKasurinen ,

Sorry for late back, you can use filter in process monitor, please refer to the below blogs:

How to Debug Windows Application Errors with Process Monitor (maketecheasier.com)

How to Use Process Monitor and Process Explorer (helpdeskgeek.com)

It may takes lots of time if you want to find any meaningful message.
