I ran the latest update on Lightroom classic and Lightroom and now the people detection on the masking function is not working. It says people not found. Is this a known issue? Is it being worked on? Anyone else running into this.

You do not give the necessary information needed, like your hardware specs and the OS (with version number) you are using. If you use Windows, then problems like this are almost always caused by outdated GPU drivers. Check the website of your GPU manufacturer for driver updates. If you use a Ndivia GPU, then make sure you install the Studio drivers, not the Game Ready drivers.
