Photoshop no longer saves back to Facebook

I have been switching back and forth from Lightroom to Photoshop for years. with no trouble at all. All of a sudden I can no longer do that. I have made no changes except for updates on both and they are all up to date. In the Lightroom file there is a  large difference between and it my Computers file.I have Windows 11, and the latest versions of Photoshop and Lightroom. I also have the beta version of Photoshop and wonder if that is the problem.?
