Stuck on 'Extracting technical information'

Summary

Trying to upload (and publish) another product on Fab.
Been doing this all week, and it’s been fine every day until now…

Added the format ‘fbx’ to the listing, as it’s the main component of the Product, and uploaded a .zip, as I have typically been doing.

Issue now is that it’s stuck on “Extracting technical information…” with no way to progress to edit the technical details, which I usually see after a short moment.

Closing the page, refreshing, deleting the format and reselecting fbx → upload gets me stuck right back there at extracting.

Anticipated Question:

Q: What formats are you including?

A: A .ZIP holding: .PNG Textures, .FBX meshes, and a .TXT Text file.

Additional Notes

• URL is obviously my product listing, so redacted the listing code where relevant; breaking it.

• You can give me the Email Address to send the .ZIP to the relevant Support Team to test the upload and/or inspect the integrity of the file(s).

Went through each mesh, modified geometry, re-exported everything and then zipped them back up.

Deleted the old listing and started anew, and ran straight into the same issue again.

It’s just refusing to extract the technical information. Not understanding this at all, they’re just FBXs with PNG textures (in the same folder layout as everything else on my store page).

I should also add that I’ve since updated Chrome, but still no luck with the listing.
