Powershell install

I am having a difficult time installing/updating my powershell modules. I noticed this when I tried installing DBA Tools moudle. Reference links are https://dbatools.io/download/ and https://github.com/sqlcollaborative/dbatools.

It's a corporate PC. But I know that I have installed other modules before in the past. Does anyone have any idea what's going on?
