Shipping was deactivated

Hi all, setting all of this up for the first time and find it super confusing. But last night I seemed to have shipping working. Then this morning it is deactivated, no email, no nothing. I wanted to edit some things anyway, did so, and now I can’t get it to activate and to my site users it throws an error of no shipping available, try later or contact support. Now I can’t launch because of this one final thing for which I can find no answer. Please help.

I’ve emailed support just now, but stressing to get this done ASAP.
