Hi,@Omkar Khamkar. Welcome to Microsoft Q&A.

The error message indicates that the faulting module causing the crash is mso99Lwin32client.dll, which is associated with Microsoft Office.

• The error code 0xc0000005 indicates an access violation, which means that the application attempted to access memory in a way that is not allowed. Check your application's memory usage and ensure that it does not access invalid memory addresses.
• The installation of Microsoft Office or its associated components may be corrupted, leading to issues with the mso99Lwin32client.dll file.
• There might be compatibility issues between your application and Microsoft Office or its components. Ensure that your application and Microsoft Office are compatible with each other.
• Try repairing the Microsoft Office installation using the built-in repair tool. You can usually find this option in the Control Panel under Programs and Features (or Apps & features in Windows 10), where you can select Microsoft Office and choose to repair it.
• Identify and resolve any conflicts with other software installed on the system. This may involve updating or uninstalling conflicting software.
• Make sure that Microsoft Office is up to date. You can check for updates using the built-in update mechanism in Office applications or by visiting the Microsoft Office website.
• If the issue persists, consider updating or reinstalling the WeldingIOTApplication.exe to ensure that it is compatible with the environment and dependencies.
