You can use mamba's much faster solver directly with conda.

  conda install -n base conda-libmamba-solver
  conda config --set solver libmamba

Mamba is great, and I use it when possible. It's probably the single best thing to happen to Anaconda in years. Nowadays it's installed automatically, but up until a month ago you had to deal with the slow solver to install it.

And fortunately it will become the default by Q4!

The point I was making is the old solver left an impression on me that SAT is slow and inefficient, that's all really :)
