I downloaded youtrack-2020.5.3123.jar
restarted YT (as an upgrade from youtrack-2020.2.7479.jar)
Now YT won't start:
[YouTrack Error] Caused by: java.lang.IllegalStateException: Your YouTrack installation contains legacy workflows that are attached to at least one project. Here's a complete list: jetbrains-youtrack-slack
But I can't detach workflows without starting YT; and I can't downgrade.
I'm stuck with a broken youtrack.
How do I detach workflows so I can start YT?
