SyntaxError after autocorrecting long line with a block and appended string

[tom-kuca]

Given the input file

Logger.error "\n\n\nBacktrace:\n\s\s" + e.backtrace.select { |line| line.start_with?(LIBRARY_PATH) }.join("\n\s\s") + "\n\n"

the command

exe/rubocop --config /dev/null --only Style/BlockDelimiters,Layout/LineLength task.rb -a

autocorrects the file to

Logger.error "\n\n\nBacktrace:\n\s\s" + e.backtrace.select do |line|
 line.start_with?(LIBRARY_PATH) end.join("\n\s\s") + "\n\n"

There is a syntax error:

$ ruby task.rb                                                                            
/tmp/task.rb:2: syntax error, unexpected '+', expecting end-of-input
...RARY_PATH) end.join("\n\s\s") + "\n\n"

No error is reported on the original file.

Expected behavior

Expected behavior is a syntactically correct ruby file after autocorrect.
