SparseLinearDML and DML with Debaised Lasso output only NaNs

[CatMitch]

With identical data, when I use DML with WeightedMultiTaskLassoCV as the final model, the output is fine (not necessarily accurate, I just mean they are numbers) whereas when I use SparseLinearDML or DML with MultiOutputDebiasedLasso, the outputs from the final model are all NaNs. The residuals appear fine however
