Lotus 10 no selector possible

Hello,
I have an update project, where Lotus 9 and Lotus 10 are changed. Together with a switch from server 2008r2 to server 2019.

Now the problem is that on Server 2019 and Lotus 10 I can’t set a selector anymore. As soon as I click on Update or Repair in Uipath and want to select something in the mail view of Lotus, this does not work. Not even the UiPath menu appears which is the normal white one when you want to set a selector. Only in the start view everything works.

I have already installed the Java bridge.

Does anyone have an idea?

Thanks

Peter
