The updated language server dependencies (@actions/languageserver and @actions/workflow-parser version 0.3.46) require Node >= 20 according to the package-lock.json, but the package.json still specifies Node >= 16 in the engines field (line 14). This creates a compatibility mismatch. Either the engines field should be updated to require Node >= 20, or a version of the dependencies that supports Node >= 16 should be used instead.
