Found an answer.

Summary of my fix:

• I removed all imports from .tsx files in my test files.
• This also includes removing imports from .ts or .tsx files that, directly or indirectly, import images (like PNGs) or CSS.
• This prevents Node.js or the Playwright test runner from trying to parse image imports, which only Webpack can handle.

Best practice:

• Only import test utilities or plain .ts files (with no image/CSS imports) in your Playwright test files.
• Never import .tsx files or any file that could eventually import images or styles.

This approach will reliably prevent "Invalid or unexpected token" errors related to asset imports in your tests.
