Ventura 13.3.1 / Time Machine Backup Slow
I recently updated my macOS to Ventura 13.3.1. Every time my computer backs up to an external hard drive, my computer applications freeze. It's affecting Zoom calls, playing web-based audio, video, working in other applications, etc. Is anyone else experiencing this problem? I'm noticing it only with the updated Ventura OS. I haven't had this problem before. I am using a 27-inch, 2017 iMac with 5K Retina display--64GB 2400 MHz DDR4 memory.
