Lightroom classic is not showing my images in the libary module after upgrading to version 15.5

Hi all. I upgraded Lightroom classic to the latest version 15.5 which is the August update and now I find that I cannot see any of my images in the libary module. Lightroom was fine before the upgrade and now I find this happening to me. I want to know if this is a bug or something else. Has anyone else experienced thins issue after upgrading to the latest version of Lightroom classic. I have enclosed a screenshot if anyone can help out a solution to this.
