Feil: Problem: cannot install the best candidate for the job - nothing provides openssl-libs needed by powershell-6.2.1-1.rhel.7.x86_64 - nothing provides libicu needed by powershell-6.2.1-1.rhel.7.x86_64 (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
See this post.
Install the proper dependencies (use dnf to resolve them), and then use the commands they give to get the binary needed.
Users installing 3rd partly software like this must understand that once you do this you own it. You installed it, if it breaks you fix it. That is more so true for this software because of where it comes from.
If other users want to help that is fine, as in no problem. But as far as official help for 3rd party stuff in general and in particular anything from M$, um, that would be a no.
