Fails to start in VSCode: "[Errno::EBADF] Bad file descriptor - ruby"

solargraph gem 0.44.3
Ruby Solargraph plugin 0.23.0
VSCode 1.66.0
Ubuntu 20.4
ruby: jruby 9.3.3.0 (2.6.8) 2022-01-19 b26de1f5c5 OpenJDK 64-Bit Server VM 17.0.2+8 on 17.0.2+8 +jit [linux-x86_64]

I have done the following

installed plugin
added gem to Gemfile and run bundle install
checked the box for "Use bundle exec to run solargraph"

When VSCode starts, Solargraph fails with this:

The only error log I can find is in the OUTPUT tab -> "Log (Window)":

... but I don't really know what this means or what command is being used to get this result.

I ran bundle exec solargraph scan, but didn't see any red flags.

I tried it with a brand-new config created from bundle exec solargraph config to make sure that wasn't the issue. Same result.
