Question Development build crashed with "Failed to load 'NVUnityPlugin', expected x64 architecture"

One of our Steam game player got crash on launch.
The full message is "Failed to load 'NVUnityPlugin', expected x64 architecture, but was Unknown architecture. You must recompile your plugin for x64 architecture."

It is very identical to this thread (which has no answer yet)
https://answers.unity.com/questions/1910222/failed-to-load-nvunityplugin.html

Here is situation:
- I built game to sell on Steam with development build (for getting full stacktrace reported on Unity cloud service)
- Unity version is 2022.1.15f1
- Client's is (probably) running Windows 10 64-bit

** I don't have crash log and probably cannot obtain one. It happened on one of my Steam player who bought my game.
From a quick search it is part of this library, which I never used:
https://docs.unity3d.com/ScriptReference/NVIDIA.NVUnityPlugin.html

Is there anything I can do for this player?

 

One of our player reported it as such in their review , maybe it was crashed by something else by this message was popped up before that.

Here was player's original message
(Translated) I am using 64-bit OS but I got this error message on launch and cannot play the game.


For now I reply to him to update Nvidia driver...

 

Update: after some time, reviewer posted an update (also in Japanese).
That after update Nvidia driver the crash is gone.

So I think this issue is solved.
