Looking at the exception, this seems to be around the build in analyzers. Seems we need some checking for an empty file in https://github.com/fsharp/FsAutoComplete/blob/72103b558d579515244992bf7c09b3d610280c60/src/FsAutoComplete/LspServers/FsAutoComplete.Lsp.fs#L61 and https://github.com/fsharp/FsAutoComplete/blob/72103b558d579515244992bf7c09b3d610280c60/src/FsAutoComplete/LspServers/AdaptiveFSharpLspServer.fs#L288.

Probably should use GetLine and return an empty string if it's None.
