I believe I just discovered a leak in the same location on my 2016 Suburban. Is this what yours looked like?

For anyone who may be following this thread, I was able to confirm there was a leak in the 5/8" A/C return line, under the rubber protector. I was able to confirm this very slow leak by pressurizing the system to 50 psi with my air compressor and using soapy water. I plan to fix it using this kit: https://www.autocoolingsolutions.com/products/ac-line-repair-kit-tr10-24
