The game crashes if you exit the keyboard after linking it, placing new blocks on the screen, trying to use it again, and then leaving, don't know if "Keyboard hooked" is intentional, but if I don't do all the steps and try to use it, it says that it needs to be linked, so I'm assuming this is a bug. Might be a mod incompatibility though because I am using a bunch of mods alongside webdisplays.

Using version 2.0.1-1.20.1 on Forge.
