Try clearing the system cache. Restart your phone..hold the volume up and power button at the same time.. release when the Samsung logo appears.. use the volume down button to select the wipe cache option.. restart your device.
My issue was in Kiwi browser only. I didn't attempt to use the clipboard in any other app often enough to find out if it was broken elsewhere. Copying texted caused SamsungSmartSuggestions and Gboard to both crash, but after I disabled SamsungSmartSuggestions I had no more issues. Hope you find a fix...good luck!
