Snap Areas doesn't work

After sleep Snap Areas sometimes doesn't work. If I restart the app, then works fine. Permissions okay.

And, how can i undo this command?
defaults write com.apple.dock workspaces-edge-delay -float 2.0; killall Dock
Maybe this is causing a bug?

macOS Catalina 10.15.2 (19C57)
BTT 3.215 (1392)

Thanks!
