    Hello @Johnny's Laptop and thank you for reaching out.

    The error message and stack trace currently provided do not contain enough information to identify the exact cause. Please provide:

    • the full error log or stack trace
    • the IDE or development environment you are using, including its version
    • the version of .NET your project targets
    • any relevant code and details about when the error occurs
    • any recent changes made to the project

    The more context you can provide, the easier it will be to troubleshoot the cause of the error.

    If you found my response helpful or informative, I would greatly appreciate it if you could follow this guide for your confirmation. Thank you.
