Nah you cannot force proprietary library that consumed by fork of viral licenced app to changed it license.

For example of this case is Apple Game Porting Toolkit which is fork of Crossover version of Wine GPL , Apple modified the code add dependency to their own implementation of DirectX's D3DMetal which is proprietary licensed library. So GPTK is composed with mixed GPL Wine app + propietary D3DMetal.

This can apply as long as the library has no references or dependencies on the application.

The illegality of Bambu Labs' actions results from the dependencies of the binary module on the AGPL app, not the other way around.
