It seems that after updating to Big Sur, I cannot save files locally on my desktop from a remote server. When I open the file off the server and then go to save as to my desktop, I get an End of File was reached unexpectedly error. I am running Reader version 21.001.20155. This error does not happen on macOS Catalina 10.15.7 so I am not sure if this is something Adobe or Apple has to fix. I will be filing a separate ticket with Apple on this matter. Thank you
