Found a solution. Go into disk management (dskmgr.msc, or simply search "disk management" in the start menu), find drive D: in the bottom half of the window, right-click > change drive letter and paths > select D: in the list and click remove. Afterwards you shouldn't get the error anymore. For some reason, Cura just cant accept that my SD card reader is empty and that it should give up on trying to read from it.
