I'm desperate for help

I am at a point where I am desperate for help. I recently updated my mac to Sonoma and keep receiving the notice "unable to establish a secure connection to Zoom." I also cannot get the Zoom download or account page to load correctly on my computer but can't get it to work on my phone and iPad just fine (so I know it has to be an issue on my Mac). I have tried everything - clearing my cookies and cache, restarting, making sure Zoom is up to date, granting all the right permissions, and security settings and deleting the Zoom app and redownloading it after removing it from the trash. I tried to contact Zoom for help but have been told that my account (the free one) "doesn't qualify for use of the chatbox or support tickets". I am desperate for help here - can any tech wizes give me some suggestions I haven't thought of?
