UnityHub don't run in NixOs

Help
1

I just tried to install unityhub (nix-env -iA nixos.unityhub), then I got a new free licence and installed unity 2020.2.1f1, but then when I create a new project (the template does not matter, in this example I used the 2D template) I get an error:

Project you are opening contains compilation errors. Entering Safe Mode allows you to resolve these errors without waiting for the rest of your project to import.

I put more information and screen shots in this bug report. Would love to know if I just stupidly missed something or not.

I do see this on start

Yes, I also get this error, it is just not a “blocking” error since at that step I can continue and create a new project after seing this error. But it may be the reason why the build fail, do you know how to fix that?
