I had a similar problem but not exactly this. You can try to change the API compatibility level under Project Settings > Player.

While searching for the solution, I found that people were switching to.Net2, but mine was .Net2 by default, so I switched to .Net 4.x and it builds successfully.

r/Unity3D on Reddit: There are 2 settings providers with the same name warning
May 17, 2023 -

Unity 2022.2.18

Full warning text:

There are 2 settings providers with the same name Preferences/Jobs in User scope.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

This warning pops up whenever domain reload happens (it seems like). Googling doesn't give me any clue what all this means. Starting from full warning text itself, and ending with what in the world Preferences/Jobs is and where it lives, and what on Earth User scope is and where it lives.

Judging by the word Preferences, I thought that issue is with my user preferences / Editor installation. But it appears only in 1 specific project. And in project folder I haven't found anything that would even remotely be related to something like "Preferences/Jobs".

When it started popping up I don't know either, I noticed it when I had my console completely spammed out by it.

I already reported a bug. I also asked in official discord server with no meaningful replies whatsoever. By chance, does anybody have any clue at least what this issue means? At least perhaps what is Preferences/Jobs and where it is on my SSD.

Edit: I blindly tried to rebuild Library folder (by just erasing it). Warning still pops up.

Edit2: The warning message with full stack trace (probably should have included it originally), no idea how to make any sense of it:

There are 2 settings providers with the same name Preferences/Jobs in User scope.
