Any help appreciated in resolving the following problem.  
I have been using VSCode with Julia 1.8.5 and all has been well. Now I am trying 1.9.0-Beta4 and coming up with error messages. These are both in pop up windows and in the output region on VSCode.  
I have been regenerating the manifest.toml file as kind of mentioned in the blog under [New Manifest Format](https://julialang.org/blog/2021/11/julia-1.7-highlights/) by removing the old one and running Pkg.instantiate(). The error messages persist.  
Some of the pop up messages are:

```julia
The Julia Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information.

```

```julia
The Julia Language Server failed to precompile. Please check the FAQ and the local output.

```

```julia
The Marketplace has extensions that can help with '.4' files

```

```julia
The Marketplace has extensions that can help with '.4' files

```

```julia
Pending response rejected since connection got disposed

```

And the first part of the output section of VSCode gives:

```julia

I had some of this. After I installed the `preview` version of the extension it worked.

I am afraid I don’t understand. I looked under extensions in VSCode and typed in Julia and nothing came up. I did some browsing on the web under VSCode Marketplace and still nothing obvious.

More detail will be appreciated.

In VSCode, if you click on the Julia extension in the extension tab, you should see a dedicated page.  
In the top, there should be a button with `Switch to preview version`, which will install the newer version that supports the latest beta.
