Lightroom won't add photos! (Mac desktop)

Hey! So lightroom randomly stopped letting me add photos or access 'recent photos' (but photoshop is fine) and after checking I realised I needed to update everything on my macbook. After doing so I opened lightroom that had been updated and STILL it will not let me add any photo's? Has anyone else had this issue and resolved it at all?  I pay a monthly subscription and that's all fine too! It is pretty urgent, please help!!
