When the bug happened this afternoon I was in 1.14.5 (I was doing a short flight), after the bug I got an update and now I’m in 1.14.6
After the warn message (18:30h CEST) appeared and after restart the sim, I got stuck into the start screen into a loop.
After close the sim (Alt+F4), and start it again, I was prompted about the “Accesibility menu” (the one about the scale of the UI of the game), and then I was promped about the License terms (like if it were a new instalation) and then the langage changed from Spanish to English.
I restarted the sim again and then a notification about the new 1.14.6 version was notified to me (19-19:30h CEST).
Best Regards!
