# Components Fail to Load with a Commented-Out Import

Lightning Web Components (LWC) fail to load when Lightning Web Security (LWS) is disabled, Lightning Debug Mode is enabled, and the component contains a commented-out `import(...)` statement (such as in a JSDoc `@typedef`). The error occurs because the legacy Lightning Locker evaluator incorrectly parses the commented text as an active dynamic import.

## Workaround

Apply any one of these solutions:

- Remove the commented-out `import(...)` or JSDoc statement from your code.
- Enable Lightning Web Security (recommended).
- Disable Lightning Debug Mode.
