I think she will appear reasonably healthy to start, although she can’t fake a strong gait coming onstage. Walking in, if they televise that as they normally do, she will not look robust, but she will be adequate.
However, she will have a lot of difficulty going strong for 90 minutes. I won’t say it’s impossible, but I think the odds are against her. I don’t think there is any public evidence in the past many many months that she has done anything steadily, strongly, convincingly on her feet for 90 minutes. As far as I know, her public appearances of the past 4 months are all limited to 15-30 min.
I doubt that she has much stamina for an intense 90 minute event on her feet, even if she does not collapse completely.
