My quickbooks premier 2020 will not open.  Got Error 3771  Status code 11104

I tried everything i could think of.  Finally uninstalled and reinstalled and still will not open and now doesn't even give me and error.  Please help.  I have work to do this weekend and intuit pages are junk as far as help goes.  No phone or chat lines open from them even tho I pay for unlimited support.  Ugh
