Commerce button disappears when in desktop Editor.

Hi everyone, I hope you are doing well. I need some help.🙃

So, When I go into the desktop editor to bring in clothing, I click on the little carrot/arrow to select Commerce, and it shows for a second but then quickly disappears before I can select anything.

I’ve tried repeating the steps a few times, but it keeps happening. Has anyone else run into this issue, and do you know how to fix it?

Thanks in advance for any guidance!
