Late answer, but make sure that you don’t have any spaces in your address and that you don’t include the bitcoin:.
So if you copied bitcoin:bc1q7ug4w4as2sefar89q057hnmxkakp58a25535ttlmurn6cncs8tms4e7gp2 make sure that you remove the bitcoin: and any spaces (maybe at the end of your address?).
So you just have to enter the bare address like for example bc1q7ug4w4as2sefar89q057hnmxkakp58a25535ttlmurn6cncs8tms4e7gp2.
