Cannot install any power modules

Question

When I try to install any powershell modules i get the same error, that a file is being used by another process. This relates to the temp folders and files that are created when downloading the modules. it is almost as if the same download is holding open the file so the install process can not install it. this is happening on all modules I try to install.

PowerShell 7.1.3

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its
InstallationPolicy value by running the Set-PSRepository cmdlet. Are you sure you want to install the modules from
'PSGallery'?

Use "Process Explorer" to find the process holding the file handle.
