Kernelbase.dll Error While HR Sync

Hi folks,

We are getting an interesting error during HR data import. Once per five minutes, we are reading our HR database to get updates or inserts for a couple of years. However, all the sudden, we've started getting this error during data import.

On One Identity perspective, the error was simple: "Processor terminated unexpected".

As I investigate on Job Server machine further, I could get a more detailed, yet still missing information. It says that StdioProcessor.exe has stopped due to an IO exception error (I have pasted the full error message below). Could you please help me troubleshoot our issue?

Product we're using -> One Identity Manager 9.1

The following are our error messages;

First One (Windows Event Viewer)

In One Identity (we are ignoring the errors in HR import processes, so the error output is sent through email):

What we tried are listed below too;

- Reinstalling .NET Framework,

- Reinstalling C++ Redistributables,

- Restarting the machine,

- Running StdioProcessor.exe with administrator privileges,

- Copying KernelBase.dll from another computer
