Yeah I already tried the solution given before to no avail as well, but I ended up getting it to work by logging in with my brothers account who also has GTA V. I was prompted with the same message at first, but I attempted to login again and it worked. After that I logged out and logged into my account and didn’t even get the prompt.
I know this isn’t a feasible fix but if you know anyone with a copy of GTA V and a Rockstar account, hat seems like your only solution so far.
