Youtrack 2021.2 does not start with "java.lang.IllegalStateException: Your YouTrack installation contains legacy workflows..."

We have incidentally attached an older workflow to the new project.

After 4 days we make server-restart and YouTrack does not start:

Is there any way that we can restore work from this 4 days? ...start YT without workflows?

  • youtrack 2021.2.19690
  • Windows Server 2012R2
  • daily youtrack- and server-backups
  • start string: "C:\YouTrack-Prog\launcher\bin\JetService.exe jetservice /debug "/settings=C:\ProgramData\JetBrains\YouTrack\conf\internal\launcher.service.settings.xml""
