Well, it looks like I may have solved the issue. It turns out that, for whatever reason, installing the Visual C++ Redistributable 2022 through protontricks into my SSE prefix as opposed to only having it in my default wine prefix has gotten the latest test DLL to work for me. It was a workaround I discovered while installing Open Animation Replacer. If there's any further tests you'd like me to run, I'm more than happy to. Otherwise thank you so much for your time, sheson. Sorry it was a problem on my end!
