ofumii commented 5 months ago

Uncaught exception in thread:AWT-EventQueue-0

java.lang.NullPointerExceptuion:Cannot invoke "java.awt.Image.getWidth(java.awt.image.ImageObserver)" because "retVal" is null

When I press the Export button, I get the above error.I don't know the cause. Could you please tell me the cause of this issue and provide a solution?

Is there a more detailed error in the console log? That's not enough information to determine what might be wrong.

I apologize. I didn't provide enough details. I encountered this error. Is there anything you can gather from this?

That doesn't look like that's an issue with jmc, I think it's more likely something wrong with your java install or maybe even your windows install. I think you should try and re install java, hopefully that fixes it.

Ah, I see! Thank you very much. I appreciate your detailed explanation and guidance.
