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

Question

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.

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.

我的问题可能和你是一样的。我使用xamarin.forms开发，启动UWP时可能会闪退。

我还不知道如何解决这个问题，但是现在能够知道的是这个错误和打印有关系，只要用户使用了APP中的打印功能，再次重新打开APP时就会闪退。我在APP中使用的打印控件是Syncfusion.Xamarin.SfPdfViewer。重新安装APP可以解决这个问题，但是打印后重新启动还会闪退。 如果有人知道如何解决请告诉我。
