I can't get rid of it

Does it crash? Is it the creative frame or a little frame?

I will close this issue for now. I need more information in order to help out.

The frame without any picture

Is it inside spawn protection maybe?

It’s a creative frame

Is there a crash? Or why can't you remove it? You can also use the /setblock command

There isn’t any form of crash, I don’t know why I cannot remove it, /setblock commands or any other similar I’ve tried don’t work.
I managed to get rid of the “indestructible frame” by removing the mod and reinstalling it after doing a “clean save”.

Can you see the frame or at least the outline?

I see a 1:1 “wooden plank”

Nope

Idk why it happened but it’s fixed now so don’t worry
