Hello @Jan5E61,

We understand that encountering technical issues can be frustrating. Is this file saved as a Cloud Document? If yes, try reverting to an older version of the cloud document (https://adobe.ly/3WIVZT5) to see if it helps. If the problem persists, kindly share a link to the file after uploading it to Dropbox/Google Drive/etc. so that we can check it on our end.

Note: While sharing the link, kindly ensure it is set to Public.

Looking forward to hearing from you.

Thanks,

Anubhav

Can you share the document? Rename the file extension to .PDF and you can upload it to the forum.

Or if not, show the contents of the layers panel?

Select one of those black shapes and show what's in the Appearance püanel?
