it looks like the game is crashing because the mod is looking for an xorg server but i have disabled xwayland.

is xorg necessary for this mod to work?

Screenshot to Clipboard uses Java's AWT library, which currently doesn't support Wayland. You might be able to fix this by using the Jetbrains Runtime as your JVM, as they've implemented preliminary Wayland support with the -Dawt.toolkit.name=WLToolkit command line argument for their IDEs.
