Hi, I have the M2 MacBook Pro, MacOS Sequoia 15.3.1 and I ran into this issue where UA Connect was not working. I tried putting the application in the bin, but it wouldn't let me as it was "running", even though It had not opened up on the screen or taskbar. I opened up Activity Monitor by opening up Spotlight (cmd+spacebar) and typing Activity Monitor in. I selected UA Connect which and stopped it from running by pressing "X". I opened it, it still didn't work. I stopped it running again via Activity Monitor, and this time when I double clicked the app again, it actually opened.
