(ArgumentError) could not call Module.*_attribute/2 because the module * is already compiled

I am getting the following series of errors on one specific LiveView component file in one project:

This small file comes from an example for a library of ours that we aim to publicize in `O(month)`, so I'm hesitant to waste time trying to make a cleanroom reproduction (i.e., I burned too much time trying to do this already). I can send the file or entire library (if needed) to whoever wants to fix this.
