Good morning,

I am experiencing difficulties on various computers when trying to install the KB5031356 update. In particular, when using applications in Internet Explorer mode from the Edge browser, I am encountering the issue that I am not allowed to access the modules of those applications. When clicking on the desired items, the corresponding pop-up windows do not open.

As an alternative measure, I have uninstalled the said update, which has made it possible for the Internet Explorer mode to function properly. I would greatly appreciate any assistance you can provide in this regard.
