However, have you tried following this instruction? https://www.reddit.com/r/HarryPotterGame/comments/11h4v1c/comment/jiom3hs/?utm_source=share&utm_medium=web2x&context=3
I'm getting the same exact error on Debian. Seems like UE4SS doesn't play well with P3R. I've followed the instructions on reddit (they typo'd the dll file tho) but to no avail.
Native linux support isn't quite here yet, so you need to do some messing about with wine.
Native linux support
Is completely irrelevant as there is no Linux build of the game

I have tried this without much luck at all, I've also tried using Ultimate ASI Loader and renaming the UE4SS.dll to have an .asi extension so it would load it (in case it was an issue with how the library hooked the DLL into the process), I've tried WINEDLLOVERRIDES, and yet, nothing fixes the problem for me. Something's up with how UE4SS functions that prevents it from even running on Proton.

While I can't comment on whether UE4SS works on the steam deck (I have no idea), I can say that it definitely works with proton, and in fact, that's I use it most of the time.
Oh and ever since 3.0, I haven't needed to use WINEDLLOVERRIDES, it just works out of the box if dwmapi.dll exists in the directory.
Yeah, I'm using it on Proton, and even without the WINEDLLOVERRIDES, it looks like the same error regarding the steamclient64.dll happens. I've tried this with Hogwarts Legacy, Persona 3 Reload, and a few other games without any luck.
IIRC this had something to do with UE4SS touching the DLL search path to load cpp mods and had to comment these lines out to get a particular game to work through WINE: https://github.com/UE4SS-RE/RE-UE4SS/blob/332eea5711d036edd428b733f27214e8128e3d96/UE4SS/src/UE4SSProgram.cpp#L394-L397

Do you happen to have a test build compiled so I can test this?

You can try this one: https://github.com/UE4SS-RE/RE-UE4SS/releases/download/experimental/UE4SS_v3.0.1-52-g7d6f790.zip In that one, we don't use SetDefaultDllDirectories.

Sweet, this seems to work without issues with Persona 3 Reload on Proton at least. Thanks!
Hi
Can confirm both the error with the normal build and the experimental build fixing it in latest SteamOS 3 stable (Steam Deck) with the videogame Video Horror Society running on Proton 9.
Thanks for this terribly incredible tool btw.
