TL;DR

The CLI crash on Windows 11 with Node v22.16.0 is likely due to an incompatible method call, and checking the newSpans.at function compatibility might provide a workaround.

Guidance

  • Verify the compatibility of the at method with the newSpans object, as it's possible that this method is not supported in the current environment.
  • Check the documentation of the _StyledLine.mergeSpans function to see if there are any specific requirements or restrictions for the newSpans object.
  • Consider testing the CLI with a different Node version to see if the issue is specific to v22.16.0.
  • Review the code to ensure that the newSpans object is correctly initialized and populated before calling the at method.

Notes

The provided information does not include the specific code that's causing the error, so it's difficult to provide a more detailed solution. Additionally, the issue might be related to a specific library or dependency that's not explicitly mentioned.

Recommendation

Apply workaround: Since the issue seems to be related to a specific method call, trying to find an alternative approach or checking the compatibility of the at method might be a good starting point to resolve the issue.
