Both times there was no solution and the topics were closed after the 30-day period.
I confirm that the issue still comes up (It’s almost July) at least in Win10.
And here’s the really interesting thing - I managed to solve the problem by deactivating and then reactivating Punto Switcher - a program from Yandex that automatically switches language input as you start to type something. I have no idea if it’s directly linked to Punto Switcher or any other keyboard tracking programs you might have, but there it is.
