I am using Sketch on Catalina. After a crash of Sketch my document (412mb) could not be opened any more (told by an error popup window).
I need this document to be opened urgently or have to redo my work for a whole week. Is there any way to repair a corrupt file - like adding any binary block to the end of the file, deleteing some cache-part in the file or elsewhere etc.?
Using Sketchtool (the first time) I get this output:
./sketchtool list layers /path/to/file.sketch

Unzipping the .sketch file works.
