ADE stopped working after upgrading to Windows 11

I upgraded my PC to Windows 11 a few days ago. This morning I tried to authorize a book through ADE and the programm crashed. I rebooted, same issue. I uninstalled the whole lot, reinstalled, still no luck. I did a deep clean, removing the keys from the registry before reinstalling a second time, didn't help.  I tried a few of the suggested solutions, no results. The programm is marked as open on the taskbar, but there is no window to be seen, clicking on it results in something flashing in the corner and that's it. I did see some books at some point but clicking on the one I needed, turned it sluggish, then the programm stopped responding. I tried running it in compatility mode and as an admin, to no avail. I'm at wits end now.  Any solutions from people who ran into the same problem ? Thank you.  @Adobe : please fix this.
