I think only the organizers could help you. If you used butler, maybe the previous versions were available, but I dont know if you can restore that during the jam.
For future reference, you could upload the game to gotm or something similar. That way the game is available to experience without the bug but the real submission unfortunately must contain all the bugs that come with the time limit and lack of testing. That is part of the challenge.
You can freely edit the webpage though, so you can upload it to gotm and link that to the itch page. That lets people play it until you can actually contact one of the admins.
