Thanks for the fast replies.
Updates are kind of done. Running as admin did the trick. A bit weird.

One of them was corrupted. Getting the advice to download again. But the download manager does not have an option for this (I see only the install (corrupted) button. Because it is not downloaded in my default download folder, I have to figure out where BIAB downloads it and probably do a manual download. Not in the mood for that anymore. It is midnight here.

There is no warning for the crash. It just freezes. BIAB only, not Windows. No idea if the update helped, because cannot do it right now. No changes and no new sound card.
