UWP app crash immediately after opening with Faulting module name: KERNELBASE.dll Event Log

Samip Dahal 1 Reputation point

Hi all,

I have developed a UWP app and uploaded it to Windows Store. Everything was working perfectly fine until I created a new self-signing certificate after the previous one expired and re-published the new changes to the store. The application after downloading and installing from the store crashes immediately after opening and leaves an event log with the below error in the Windows Event Viewer. The same issue occurs when installing through a side-loading build.

I have tried all methods suggested online(running system scan for corrupted files, register dll, use dll file from another system, etc). I have also uploaded an image showing my windows version. Any help will be appreciated. Thank you.

    Hi there,

    As it seems you have tried all possible solutions (running system scan for corrupted files, register dll, use DLL file from another system, etc) the only option would be to do an in-place upgrade.

    How to perform an In-place Upgrade with Windows 10 Step-by-Step Guide

    The file KernelBase.dll is a DLL file stored in the system folder of the Windows operating system. It is created automatically during the installation of the Windows operating system. KernelBase.dll is used to launch .exe applications. When it is corrupt, you will get .dll missing or not found error when you start the programs.
