I have screen session "main", started in /dev/ttySAC0 and sh, started in /dev/ttySAC0 (outside screen session) with input, output and error streams, redirected to pseudoterminal /dev/pts/1. When I attach to /dev/pts/1 terminal and try to run screen -r main, it fails with:

WriteMessage: Bad file descriptor

But creating new screen session with screen works fine. Furthermore, if I run screen -r main in this screen session, I got screen with my saved session in another screen session. It's not usefull, but it's works.

Even if I starts new session in /dev/pts/1, detatch from it and try to revive it, I got same error.

Run screen -d, find the screens and run screen -R [screen_name].

Try adding the line defnonblock on to your ~/.screenrc file.

When I began having the same problem I found a few posts mentioning that it fixed their issues. It fixed mine.
