Powershell crashes on opening and I can't figure out why.

[u/Objective-Round-8617]

Hi everyone, whenever I try to open powershell, it instantly closes. When I open a new terminal in VScode, I get this error:

Windows PowerShell terminated with the following error:

Could not load file or assembly 'System.Management.Automation, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The module was expected to contain an assembly manifest.

Any help would be greatly appreciated. I have tried repairing my windows installation with sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth. I don't really know much about powershell. When I don't use VS Code it doesn't even give any error code it just flashes on the screen for half a second and closes.

If this looks familiar to another person's post upon Googling it is because I am having the exact same problem and experience to a tee, so I copied some of their sentences. https://www.reddit.com/r/PowerShell/comments/1gueufj/powershell_wont_open_and_i_cannot_figure_out_why/
