Open Creative Cloud desktop application, click on the Settings button at the right top corner, go to Preferences -> General Tab -> Settings and uncheck "Launch at Login" option.
This should help you.
Thank you for your response. That solved the problem.
I do have a second question that maybe you know the answer to. Since I have the stand alone version of Lightroom, why do I have to stay signed in to Adobe? My stand alone version will not run without being constantly signed in. I tried contacting Adobe and wasted 3+ hours texting back-and-forth, but nobody could give me an answer to my question. Thanks again.
For the stand alone Lightroom you don't have to be signed in on creative cloud desktop application.
as its stand alone so its separate from the cloud version. even if you will uninstall creative cloud Lr license version will work.
