RuntimeError: DataLoader worker (pid(s) 22100) exited unexpectedly

[am-official]

Dear and Near,

I tried all the possibilities. But no luck. Could anyone help me to figure out the issue? Your help is very much appreciated!

I am using windows 11 Pc with NVIDIA GeForce RTX 3090 GPU

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

The above exception was the direct cause of the following exception:
