Submenus issue with emClient 10.4 - no submenus

I just installed an update and it seems there musts be some bug related to popup menus. Almost all menus do not open submenus, for example, when message is opened I want to navigate to menu → format → [no submenu], or menu → tag → [no submenu]. Can anyone else reproduce the issue?

And I tried 10.4.4209 as soon as I found it in the other thread. Does not fix anything for me.
