P.S.:
I look at the error trace and see a path that does not exist in my system: D:\Work\mRemoteNG\1.78.2-dev\mRemoteNG\...

Start with mRemoteNG/UI/Window/ConnectionWindow.cs at Prot_Event_Closed, especially line 780, and trace the close path into mRemoteNG/Connection/Protocol/ProtocolBase.cs at CloseBG, line 156. Reproduce closing a tab with open connections and follow the disposal and invoke behavior. Done means the application no longer crashes in this scenario.
