Weird error while training a model with tabular data!!!! Some problem related self.log_dict

Bug description

The code can be accessed at https://www.kaggle.com/code/vigneshwar472/notebook5a03168e34

I am working on multiclass classification task and want to train a nueral network with pytorch lightning on 2x T4 GPUs on kaggle notebook.

Everything seems to work fine but I encounter this error when I fitted the trainer.

Training Step of lightning module

def training_step(self, batch, batch_idx):
        x, y = batch
        logits = self(x)
        loss = F.cross_entropy(logits, y)
        preds = F.softmax(logits, dim=1)
        preds.to(y)
        self.log_dict({
            "train_Loss": loss,
            "train_Accuracy": self.accuracy(preds, y),
            "train_Precision": self.precision(preds, y),
            "train_Recall": self.recall(preds, y),
            "train_F1-Score": self.f1(preds, y),
            "train_F3-Score": self.f_beta(preds, y),
            "train_AUROC": self.auroc(preds, y),
        }, on_step=True, on_epoch=True, prog_bar=True, sync_dist=True)
        return loss
