Can’t Debug In RubyMine After Update?

I found that an issue in Bootsnap conflicting with ruby-debug-ide (and others). The solution is to not enable Bootsnap during debugging. You can either comment out require "bootsnap/setup" in Boot.rb, or replace it with this line from the link:

require "bootsnap/setup" unless ENV["RUBYLIB"]&.match?(/ruby-debug-ide/).
