Is Nix single user broken for others?

Help

I’m hitting often the following bug which I have filed an issue for.

Curious if others are seeing the same issue or it’s something else.

I believe it’s a regression in Nix, specifically single user installs.

I don’t know how to get more visibility on this – it’s a pretty bad experience.
Nothing obvious shows up in my strace also
