gr-dsd is just a thin wrapper around DSDcc, which does all the demodulation. I'd suggest asking about this problem there.

gr-dsd block is not supported in 3.11

gr-dsd should work fine, including with GNU Radio's main branch.

I'll close off this issue for now, since it appears to be a problem with the underlying DSDcc.
