As I said earlier, the House Ethics Committee is still obligated to continue the investigation and establish the facts and to talk to the alleged victim. No way the investigation ends just because she decides to resign rather than face the process.
Will they continue? Probably not if the alleged victim does not want to go forward, but if she makes a claim, then the House is obligated to respond to it and pay damages/settlement if proven. I know there was a lot of talk about ending the slush fund there but I dont know that it was ever actually changed. Possible. But I have not seen confirmation. Contrary to popular opinion, I think Congress should be responsible for payment, not just the individual if it can be shown that they have continued to look the other way, as we all know they have. Word in the media is that Pelosi moved her out, which would be a defense on her part but still it would require an investigation to establish the facts - even though Thunderthruple has left.
