We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Perhaps you could remove the constraints before writing the matrices?  In a modal analysis it's common for the model to be unconstrained, so that shouldn't be an issue.
