          As designed, Jenkins 2.105 introduces XML 1.1, so you cannot just replace WAR files to downgrade the instance. Actually there is no reliable way to downgrade excepting doing a backup.

          Please also see https://jenkins.io/doc/upgrade-guide/2.107/#xml-files-are-now-stored-as-xml-1-1 , which may give you some hints how to resolve the issue
