Invalid filename characters exception on uploading image

Hi. I am using windows 10 & venv & python
this is my code to upload image to wandb

wandb_log["Image/train_image"] = wandb.Image('tmp.jpg')
wandb.log(wandb_log, step)

the full directory of image is “C:\Users\이준혁\Documents\Github\terenz\tmp.jpg”
However it creates this error

Media Image/train_image is invalid. Please remove invalid filename characters

reinstalling wandb did not help to solve this problem.
what should I do?
