The error code 0xc0000374 typically indicates a heap corruption issue, and it's a bit generic.

Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check for Windows and .NET Updates: Ensure that your Windows operating system and .NET Framework are up-to-date with the latest patches and updates. Microsoft frequently releases updates to address known issues and improve stability.
2. Review Recent Changes: Since the issue started after a specific date, review any changes made to your application or the environment around that time. This includes updates to dependencies, libraries, or any modifications to the code.
3. Analyze Crash Dumps: If possible, analyze crash dumps generated during these crashes. Tools like WinDbg can help you analyze memory dumps and identify the root cause of crashes. Look for any patterns or specific code paths leading to the crash.
4. Check Event Viewer: The information you provided is from the Event Viewer. Check for additional information in the Application or System logs. There might be more details or specific error messages that can help diagnose the issue.
5. Memory Issues: Heap corruption often indicates a problem with memory. Check for any memory-related issues in your application. Ensure proper memory management, avoid buffer overflows, and consider using memory analysis tools.
6. Update .NET Framework Version: If possible, consider updating your project to a more recent version of .NET Framework. This might include migrating to .NET Core or .NET 5/6, as older versions may have known issues that have been addressed in newer releases.

I hope that helps you.
