Unable to log in since latest patch 11.1.5

Have been playing with no issues for years. Since Wednesday’s (23.04.25) patch 11.1.5, I can log in but I just get a flashing black screen (menu bar appears and disappears) and the music plays. However I cannot progress to the character selection screen.

Try this maybe.

Thanks for the tip. However, Battlement updated itself again and that seems to have solved the problem.
