Thanks for this, I just ran into this exact problem.
My quick fix was to manually upload the folder of Elementor CSS.

@damashe, glad you could use it. I'm not sure you'd need to upload the folder. I believe simply visiting the pages that had changed should generate the css files. I know it does if they don't exist, but I can't remember if it will regenerate existing files. But then you could just go to Regenerate CSS from the Elementor > Tools menu.

Thanks! Works like a charm.
