Ruby Solargraph stuck on "mapping workspace" loop

Describe the bug When starting the Ruby Solargraph language server, the status bar shows that it is stuck on a “Mapping workspace… Mapping complete” loop and never activates.

The LSP log panel shows that Solargraph is restarted repeatedly:

To Reproduce Steps to reproduce the behavior:

1. Open a folder with a Rails project in it
2. Enable the Solargraph LSP server through LSP: Enable Language Server Globally > Ruby
3. The server is stuck on a “mapping workspace” loop

Expected behavior The server is not stuck on a loop and activates eventually.
