I can't paste any image on my computer after I copy it after an update

All worked fine before I assidentally updated. Befire, I clicked rmb and then "Copy" and then I could click on a desctop or folder with rmb and "paste". Not the "paste" field id grey like it never been copied in the first place, even though I can paste the image into paint or messanger or anywhere else. I don't want any workarounds like "save as" every time I want to save something. How do I change it back Everything worked fine before I accidentally updated. Before that, I would right-click, hit "Copy" and then paste it on the desktop or in a folder. Now the "Paste" option is greyed out, as if nothing was ever copied, even though I can still paste the image into paint messenger or anywhere else. I don't want workarounds like using "Save As" every time. How do I change it back?
