Hello,
For this error, C# provides an official document that explains the cause of this problem in detail. You can refer to NullReferenceException Class. for details.
How can I find where the error occurred?????
If there is no specific line number, you can add breakpoints to the initialization method, asynchronous method, and multi-threaded method in the application and perform single step debugging to find the specific cause.
Please refer to Navigate code in the debugger using step commands for more details about Visual Studio debugging.
Best Regards,
Alec Liu.
