Any method to run gdal will be of great help :)

On Windows, because conda-forge relies on some package built with defaults blas (like scipy) one must use the defaults channel on top of conda-forge and activate conda's new strict channel feature.

One can do that with:

conda config --add channels conda-forge
conda config --add channels defaults
conda config --set channel_priority strict

Then you can try to re-install your stack. Note that on Linux and OS X we recommend the opposite order of channels.

This is the conda package for gdal, so no. There is no way to solve it without conda :-)
