Site logo only displaying on desktop

Hi, my site logo is only displaying on desktop view. This started happening after installing a menu plugin (Superfly 5), but even after deactivating and uninstalling the plugin the problem remains. I have reached out to the plugins support but there is an automated response that unfortunately due to the war in Ukraine their support is limited and delayed, so any help would be very much appreciated from users here. Thank you.
