language server crash when starting extension #945
Description
Describe the bug
The language server sometimes crashes at startup. This causes the language-specific features to no longer work.
The wrong access seems to happen in the following file: // ../../node_modules/langium/lib/lsp/document-update-handler.js.
The stacktrace is attached below.
