Additional information

No response

Reproduce the failure in the Windows Node.js REPL with the standalone import input, then trace the REPL path through internal/readline/emitKeypressEvents and the Acorn parseImport stack shown in the report. Done means entering import no longer crashes the REPL, with regression coverage for this input.
