I try to install a library and it shows this and never resolvers. I am on a Windows 10 and do not know what is wrong

Same problem here! I tried updating conda and re-installing zstandard without luck. What else could it be? Many thanks!

Thanks a lot, it works for me too. My mamba installed on base env of conda is come from conda-forge channel while the other conda packages are from official channel, that's probably why the problem occurred. BTW, mamba officially suggest should not install on existing conda but install mambaforge.
