[DEBUG][logstash.runner ] *path.config: "C:\\busapps\\rrsb\\gbl1\\logstash\\7.0.0\\bin\\pipelines"
That is a directory. logstash will concatenate all of the files in that directory to form the configuration. Every file. No exceptions. If there is a java heap dump in the directory then logstash will try to parse it as a configuration file.
Other messages then logged are
Config string {:protocol=>"file", :id=>"C:/busapps/rrsb/gbl1/logstash/7.0.0/bin/pipelines/logstash - Copy.conf"}
Config string {:protocol=>"file", :id=>"C:/busapps/rrsb/gbl1/logstash/7.0.0/bin/pipelines/logstash.conf"}
Config string {:protocol=>"file", :id=>"C:/busapps/rrsb/gbl1/logstash/7.0.0/bin/pipelines/logstash_bkp.conf"}
So it merges those three files to form the configuration. The error is at line 68, which is in the first file. Adding quotes around the passwords in logstash - Copy.conf fixes the errors, but you probably want to move the backup files to a different directory.
