After you change the setting, you'll probably have to restart VS Code and then the dependency will install for you, then it should work normally again.

I tried that and it didn't fix the issue for me. Looks like OmniSharp is looking for DOT_NET_ROOT. Downgrading back to 1.24.4 works for me. I'm not going to expect this extension to fix the issue considering Unity has fallen so far behind the C# eco system.

@AlejandroHuerta If you are doing Full Framework development on Windows (omnisharp.useModernNet: false) then you will need to install the Visual Studio MSBuild Tools.

Quick Solution for every platform (Windows, Linux, Mac)

• Set VS Code update mode to 'manual'
• Disable Windows Background Updates
• Downgrade the VS Code version to February 2022 (version 1.65)
• Downgrade the C# extension version to v1.24.4

everything will be fine 💯

That fixed it for me. Thank you.
