Problem first use of ihp-new on Windows 10

Hello,

I tried to install IHP on windows 10 using the doc : https://ihp.digitallyinduced.com/Guide/installation.html
I installed :

- WSL
- Ubuntu 20.04
- Made : sudo update and sudo upgrade then sudo apt install git curl make xdg-utils -y
- Created : sudo mkdir -p /etc/nix
- Created : /etc/nix/nix.conf
- Installed IHP : curl -L https://nixos.org/nix/install | sh

Everything ok up to here.

Then I started a project :

- ihp-new blog

That made that error :

**propagated-build-inputs: /nix/store/z856a8dzgp75jaswjsh0bw77svsd9jxh-wai-cors-0.2.7/nix-support/propagated-build-inputs
ghc-pkg: Couldn't open database /nix/store/31170mzlvjrhhl380kv4lj66dqpgpzxa-ghc-8.10.4-with-packages/lib/ghc-8.10.4/package.conf.d for modification: {handle: /nix/store/31170mzlvjrhhl380kv4lj66dqpgpzxa-ghc-8.10.4-with-packages/lib/ghc-8.10.4/package.conf.d/package.cache.lock}: hLock: invalid argument (Invalid argument)

error: build of '/nix/store/rk3331w92vvkwkdaq35360bb7yd603b6-ghc-8.10.4-with-packages.drv' failed**

What is the problem ? Is it a bug ?
The documentation is great but the part of installation which is not at the same great level of the rest.
Any help should be appreciated.
