96237.422:013c:0140:err:combase:RoGetActivationFactory Failed to find library for L"Windows.Graphics.Holographic.HolographicSpace" might be the same issue as https://github.com/ValveSoftware/Proton/issues/6533
It looks like it's loading the library but failing around holographicspace_interop_CreateForWindow. That function needs an implementation most likely. Would you be able to test a patch?

I already refunded the game but I would be able to test a patch using the other title, Desperate: Vladivostok. Would that be ok?
A bit late there, but I'm willing to test things and give logs about it.
I'm a Monado+OpenComposite user however, no ALVR one, as I have a Valve Index.
Shouldn't change anything about this specific Proton issue however.
@mohamadaljaf Hi, I found a key for Pirates VR: Jolly Roger very cheap and I bought it, so I have the game again. Tried with Proton 9.0-4 and GE-Proton10-17 and it crashed with the unreal engine dialog and the same issues. Is there any proton build / version that do you want me to test it with? I'm kinda free this week so I can perform whatever tests you need.
0001-windows.perception.stub-Implement-IHolographicSpaceI.patch
Hi, I had time to work on this patch. Let me know if it helps. Please post the log when you test it.
Proton_10.0 branch.
Hey, @mohamadaljaf -- compiled the proton_10.0 branch with your patch (it applied cleanly) but still no good, it presents the unreal engine error dialog:
Note: running on SteamVR via Steam Link on my Meta Quest 3.
Here is the proton log for that run:
0002-windows.perception.stub-Implement-IHolographicSpace-.patch
0003-windows.perception.stub-Stub-some-functions.patch
Thanks, it looks like it's going to the next step and then failing on another function. I was going to send another patch earlier about that exact function but wasn't sure if it would call it.
From the log:

I attached a patch that returns a NULL adapter for holographic_space_get_PrimaryAdapterId. Also attached another patch that then fakes success for the rest of the functions in the interface, but it's unlikely they'll be called with a NULL adapter. Hopefully the first patch will be enough.
I don't know why UE4 games think Mixed Reality is present. AFAIK these games are not exclusive to Mixed Reality, right? Please attach a log with +perception after testing.
Lastly, if it still doesn't work with the patches then you could try a workaround by deleting the Mixed Reality DLLs in the game's directory. I don't know how deeply integrated they are, but depending on that you can also try making empty files of those DLLs in case the game checks for their existence.
Some of the them from your log, first one is likely most important:

@mohamadaljaf you're amazing! Your new patches MADE IT! Pirates VR: Jolly Roger is working now, but also Desperate: Vladivostok! I'll prepare my proton build to be used by everyone, with glowing credits to you, thanks! Are you going to submit these patches to be included in wine/wine-proton?
I published my build for Pirates VR and Desperate: Vladivostok here: https://github.com/Patola/wine/releases/tag/protola-10.0
@Patola Awesome, glad it worked. Thanks for the kind words. :)
Yes, I'll make a merge request for upstream Wine after I add some tests.

Reproduction
(Happens the same on proton 8 and 9)
Two separate proton logs are attached, one for 8.0-5, the other for 9.0-4, clearly indicated on the filename. The game prefix on compatdata was purged between each attempt. Proton 8.0-5 was attempted because Proton 9 has the VR code rewritten and some games fails due to that.
