Im having this same issue! Using Windows 10 with WSL and "native" Ubuntu though, not using MSYS.

Anyone have any ideas? I'd really like to try out this program...looks incredible.

Hello.

I encountered the same issue... and solved it: this is due to a bad version of esp-idf.
As stated in the README file of lws-esp32-factory, you need to force the version in esp_idf directory:

$ git reset --hard 17ac4bad7381e579e5a7775755cc25480da47d97
$ git submodule update --recursive

(WARNING: the version hash may be updated in the future. please verify in the README file).
Then you can rebuild your lws-esp32-factory without errors.
