Unable to load System.Text.Json.SourceGeneration

[eun-infare]

In some cases when trying to list code actions in Neovim I do not get anything as if there isn't anything to fix. However, the response I get from the server is an error with a stack trace:

 ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Text.Json.SourceGeneration, Version=8.0.9.8001, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

I installed the language server through Mason and also tried building from source on my Windows machine, same result
