Ok... after creating an obsession and getting involved in searching for everything I could find about this VN, I came to the theory that the discord server was closed, I came to this conclusion when trying to find it by searching directly on discord.
Apparently I managed to find the name of the VN artist but when I tried to search for him I came up with nothing. I couldn't find it no matter how hard I searched for your account.
This VN has probably already been abandoned because when the discord server itself closes down where creators are most likely to communicate with their community and among themselves, they have most likely retired and do not intend to continue with their creation. For me it's still just a theory, but I'll keep looking for the VN artist who is still the best chance I have to find out what happened.
I will try to find him but it is not certain that I will achieve anything since if it turns out that his account is closed there is nothing to do. Also, I still have my doubts about my own theory since the Patreon is still active and has not been closed, so I will remain hopeful about this vn until one of the creators themselves confirms that they have withdrawn. Only when they do that will I lose hope in this beautiful VN, but until then here I share with you the only clue I have. (I don't know if it's okay for me to publish the name of the person who published this like this, that's why I cut it out.)
Luck, I will start for a whi investigating and waiting for some clue that can help me
