Theme file upload problem

Developer help
1

When uploading a theme, “Content-Type” is set to “application/x-stuffit”.
This issue occurs equally in Chrome (89.0.4389.90) and in Explorer and Microsoft edge.
Same occurrence on ghost v3 and v4.

I don’t know what’s the matter. I searched it a lot but couldn’t find the suitable solution.

It seems like you might have the stuffit app installed, and it’s messing with file mime types. You might want to try another computer or uninstall the app

Thank you for the comments.
In a different environment, the test confirmed that my computer was a problem.
