Menubar menu keeps disappearing

I am running v1.4.0 of the app on OSX 10.14.2. Whenever I close Cryptomator so it keeps running in the menubar, I cannot get it to open from the menubar as shown below as the menu keeps disappearing. The only workaround is to double click on the app agin n Applications and then the menu stays up. Any ideas, why this happens?


This is a know bug caused my MacOS Mojave:
