If the game would startup on the main menu (as it should), with the language option directly available
this would be acceptable.
But for some reason the game throws you into a lengthy dialogue before you get access to the options menu.
Even without the automatic switching of language that is an altf4 moment.
and no it doesnt the first screen is Languages O.o on first time load. That is under the assumption you purchased it via itch, or steam or patreon, but if somebody bought it and ran it first on a PC that had recognized german and then uploaded it, that would be the simplest and easiest explanation... but nobody would ever do that right?
