Visual Studio Code Intellisense

I've been working on this project for a while now, I was taking advantage of four extensions in vs code, the c# omnisharp extension, unity tools, the unity debugger, and unity snippets. These all worked well for the longest time, and now suddenly unity tools and omnisharp do absolutely nothing. I've tried deleting and reinstalling extensions and all that, manually and through vs code. I believe my problem lies with omnisharp, as whenever I try to download it this is my omnisharp log

 Failed to spawn 'dotnet --info'

as you can see it says 'failed to spawn dotnet --info', and I think this is the problem. I've been at this for so long and it's really frustrating. Please Help!!!!
