HTTP error on file upload

[eeji]

While submitting a new revision of an existing style I get "HTTP error" while uploading the .zip file. It's only happened with this one style, my others have uploaded fine. I have also tried repacking the zip in case it got corrupted, but the error persists.

Page error occuring on: https://www.phpbb.com/customise/db/style/breeze/revision
OS: Kubuntu 24.04
Browsers tried: Chrome 126.0.6478.61, Firefox 126.0.1

screenshot:

the offending style file:
breeze_1.1.9.zip

update: I have just tried attaching the file on the styles validation discussion topic and it has again failed with the same error. I tried a different zip which uploaded fine so I suspect there may be a problem with my styles zip file?

I tried to submit and got the same error

If you look in the Network tab of the browser (Dev Tools - F12) does it show any additional information about the error on the request?
