I also just recently found out that adding the "Microsoft.Expression.Drawing.dll" file from the LSPDFR download to the game directory fixes the problem. The RPH download does not have this file.

I ended up being able to open RPH by installing LSPDFR instead of basic RPH. I don't know why it wasn't opening. I guess some file in LSPDFR is allowing it to run. I don't play with LSPDFR so I turn it off in plugins but it's certainly a weird fix. I actually talked to some moderator about it on discord and all he said was "it's your system, but I'm not here to explain that." Lmao. Also, I tried many things before this, vanilla game with no mods, AV off, all that jazz. There's actually quite a lot of people with this exact same problem on the discord and the forums. Nobody has really said what is causing it yet.
