After Effects 17.5.1 which I have used consistently (nearly every day) will no longer open. Icon bounces, then stops - no splash screen. I also have 22.2.1 and 16.1.3 available, but the same thing happens with those. (Occasionally 22.2.1 will show the splash screen but freezes there.) No idea how to get help or what more info to give, but if anyone has suggestions, please let me know.
