Preferences lost after update to 6.1.5

Hi guys,

Yesterday I updated it to 6.1.5 and because all tests were failing I had a look into the Preferences and also the the settings of the projects and I discovered to my surprise that all settings were gone. Everything!!
I don´t know in which category to save this topic but because affects the web and mobile testing I used this channel.
Did anyone have the same problem? I am a Mac User Mojave 10.15.5.
