Is this exactly the file you imported? You mentioned it is compressed, so I'm guessing you compressed it to upload it here, but I need to take a look at the original file (the one that Tropy fails to consolidate). If you can view it, is there any chance you modified the file in a different program, after importing it into Tropy? It's possible, for example, that this other program changed the embedded metadata that Tropy now fails to consolidate it, even though it displays just fine.
In any case, if you could send me the original file that we be a big help. You can send it to me at firstname.lastname@example.org if it is too large to upload here.
By the way, the project file above is an empty project, it's not the project you're working on. (You can find the project file by right-clicking in the sidebar and selecting 'Show project file...'.
