The individual steps sound ok, however, if you project 20.000 to 2D, the results you got look very reasonable. I'm not sure about UMAP, but I think for tSNE, it's recommended to have low dimensionality, something more in the order of 32 features. I would probably try to adjust the architecture, as other comments have suggested

You are right, both tSNE and UMAP documentation recommend going to 30-50 features before using them. In this case the result is quite similar to the one I found, though.
