Hello, The problem is that yang-lsp process is failed on invalid data.
It is expected that LSP diagnostics are published.

Example: module.yang

module module {
    yang-version 1.1;
    namespace urn:ietf:params:xml:ns:yang:module;
    prefix module;

    include module;
}

submodule/module.yang

submodule module {
    yang-version 1.1;
    belongs-to  module{
        prefix module;
    }
}
