first it is NOT in an erroneous state whatsoever: qjackctl is active and running in pure client mode, probably due a genuine-jackd service is already up and running OR it's running under the pipewire-jack substitution environment--both cases are perfectly normal situations.
second, the exclamation mark icon is a temporary notification icon telling you the application is being minimized to the system-tray icon and it should persist for a brief period of time only (usually 6 seconds or so...) -- if you don't want this or you're using a desktop environment that does not support the system-tray or notification area icons you may well disable the said feature (uncheck Setup > Misc > Enable system tray icon).
