I haven't put to much thought on it, but it might be that the problem
is mathematically ill-posed.
Fro the generalized eigenvalue problem you can check, eig, eigs and gsvd.
Also these guys seem to have been faced with your problem
https://arxiv.org/pdf/1507.05703.pdf
They provide algorithms to check if the problem has a solution. Maybe
you want to implement that and share it with everybody.

If you get no mor answers form here, you can try stack overflow mathematics.
