I am running the latest version of LRC, but is will not open up. It acts like it is opening but only shows up in the task bar. I am also running the latest version of mac OSMonterey. Any help would be appreciated.
Apple changed the security requirements in MacOS Monterey. Go to MacOS 'System Settings - Security & Privacy' and add Lightroom Classic and Photoshop to "Full Disk Access". Click on the lock icon to unlock the settings, then click on the plus icon to add Lightroom Classic and/or Photoshop if it isn't already listed. If it is listed, then just enable the checkbox.
