R Client Language Server erroring in VS Code from missing Content-Length property

I am running VS Code on a remote server to develop R code and analyze data. I have the Remote Development extensions installed on my local machine and the R extension installed on both my local machine and my remote server. Whenever I have a file with R code open, I get a constant stream of pop-ups from the R Language Server Output with messages that look like the following:

[Error - 10:07:44 PM] Client R Language Server: connection to server is erroring.
Header must provide a Content-Length property.
{"{\"jsonrpc\"":"\"2.0\",\"id\":30,\"result\":[{\"range\":{\"start\":{\"line\":41,\"character\":0},\"end\":{\"line\":41,\"character\":4}},\"kind\":1},{\"range\":{\"start\":{\"line\":55,\"character\":12},\"end\":{\"line\":55,\"character\":16}},\"kind\":1},{\"range\":{\"start\":{\"line\":56,\"character\":21},\"end\":{\"line\":56,\"character\":25}},\"kind\":1},{\"range\":{\"start\":{\"line\":57,\"character\":20},\"end\":{\"line\":57,\"character\":24}},\"kind\":1},{\"range\":{\"start\":{\"line\":58,\"character\":13},\"end\":{\"line\":58,\"character\":17}},\"kind\":1},{\"range\":{\"start\":{\"line\":59,\"character\":15},\"end\":{\"line\":59,\"character\":19}},\"kind\":1},{\"range\":{\"start\":{\"line\":60,\"character\":4},\"end\":{\"line\":60,\"character\":8}},\"kind\":1}]}Content-Length: 37"}

The error seems to be specific to remote development in R -- I do not get these errors when I am developing locally or when I have remote files open in other languages.

Does anyone have any suggestions on what might be wrong? I am not entirely sure how to troubleshoot this. I am using the native R terminal (not radian) and have httpgd installed.

I have the following in my remote VS Code settings:

{
    "r.libPaths": [
        "~/R/x86_64-pc-linux-gnu-library/4.4"
    ],
    //"r.bracketedPaste": true,
    "r.rpath.linux": "</path/to>/x86_64/bin/R",
    "r.rterm.linux": "<path/to>/x86_64/bin/R",
    "r.lsp.use_stdio": true,
    "r.lsp.debug": false,
    "r.lsp.diagnostics": true,
    "r.sessionWatcher": true,
    "r.plot.useHttpgd": true,
    "r.session.watchGlobalEnvironment": true,
    "[r]": {
        "editor.wordSeparators": "`~!@#%$^&*()-=+[{]}\\|;:'\",<>/?"
    }
}

I have tried to enable r.bracketedPaste and r.lsp.debug but can't get any additional information.

I have the following in my R sessionInfo():

I also tried to set up the language server following this blog post but didn't get any difference in results. I have the following in my .Rprofile from following those instruction:

if (requireNamespace('languageserversetup', quietly = TRUE)) {
  options(langserver_library = '~/languageserver-library')
  languageserversetup::languageserver_startup()
  unloadNamespace('languageserversetup')
}
