Conan is crashing while installing xmscore

[STB0001]

I am using the Microsoft WSL version of Linux and am trying to install xmscore. Conan, Python3, pybind11, and CMake are all installed.

I am showing the commands to download and install.

stboerne@DESKTOP-974NBDN:/Programming/ThirdParty/xmscore/build$ python -m pip install git+https://github.com/Aquaveo/xmsconan@stable

Any suggestions to complete the installation and building of the xmscore library?

Thanks in advance.
