Stack error

Hello everyone :slight_smile:
I have a problem with stacking. When I try to create a stack, it returns an error (shown in the picture). Do you know why comes to this and how is it resolved?

For any processing, the program returns an error. Yesterday, with the same scenes, it worked.
I restarted the program and still returns an error.

Are you sure you’re not running out of disk space?

I didn’t had enough space on disc. Thank you :slight_smile:
