Cinnamon-settings-daemon update breaks desktop

My laptop has a 4k display, but I have it set to 2560x1440. After getting a couple of cinnamon updates a couple hours ago, I restarted and my display came up at 4k. I tried to set it back to 2560x1440, but this yields an error popup saying the configuration cannot be applied (image attached). Also, the panel at the bottom of the screen should have some icons at the bottom left (menu, firefox, terminal, etc). These seem to be missing from the screenshot @Mystic uploaded as well. These icons are not shown, but they still seem to function. For example, clicking in the bottom left corner still brings up the menu, moving the mouse to the right a bit brings up a tool tip that says ‘Firefox’ and a box is drawn as if to highlight the icon that should be shown there. I can’t figure out how to get a screenshot of the menu, but there are no icons shown there either, although if you click on the right spot the functionality still seems to be there.
