Airdrop "Failed to Save" From Macbook Pro to Iphone

After a recent update (sigh) I almost always get an error message when trying to Airdrop a screenshot from my Macbook Pro 2019 to my iPhone XR. I used to be able to do this without any trouble at all as long as my phone showed up in the Airdrop list.

Now, on my phone I get an error message that says something along the lines of: Failed to save, do you want to save this as a file in icloud instead?

No. No I don't want to save as a file in icloud instead. I would like my image to save in my camera roll as it has done without a problem for years until a recent update.

Does anybody know how to fix this problem and why it started?
