Describe the bug

When running nix develop it stops with error: Nix daemon disconnected unexpectedly (maybe it crashed?). In daemon logs I can see

$ journalctl -u nix-daemon.service -n2
Feb 26 19:46:26 voyager nix-daemon[1567]: accepted connection from pid 3366293, user t4ccer (trusted)
Feb 26 19:46:57 voyager nix-daemon[3366304]: nix-daemon: src/libstore/build/derivation-goal.cc:326: void nix::DerivationGoal::outputsSubstitutionTried(): Assertion `false' failed.

I'm sorry for not being able to provide more details because after waiting ~30 minutes it stopped happening (probably remote builder and binary cache caught up and substituted before hitting this) and I cannot reproduce it myself now. I hope that it still may be a valuable report.

Expected behavior

It doesn't happen.

nix-env --version output

nix-env (Nix) 2.19.3
