Reproduction steps

1. Trying to slice a new project with several models - I keep getting an error: "Slicing failed with an unexpected error. Please consider reporting a bug...". I have already done several of the same model types many times with no errors.
2. I removed a few models to reduce the size of the file.

Actual results

Still halts during slicing and gives me the same message.

Slicing to work

First thing when encountering any slicing issue is to make sure you're up to date. 5.4.0 released a long while back now - the current version is 5.10.2, with 5.11.0 undergoing public testing. Notably a common slicing fault was corrected with 5.7.0's release in April 2024, but every new version tends to fix something.

Should this still fail, a copy of the project itself will be required for any further diagnostics. Newer versions of Cura also include an option in the Help menu to export a package specifically for tech support that contains additional details.
