For some reason, my project started to drop errors on build in Visual Studio. Here are the main issues from logs:

```auto

```

I was trying to figure it out, but this repeats even for blank projects started from scratch.

I updated the Visual Studio to the latest version not that long ago; that may be the only difference that I can think of that might have caused it, but I rolled back the version, and the build error persists.

Any ideas?

There seems to be an outdated dependency in there.

As a workaround, edit the the .csproj file (C:\Program Files\Epic Games\UE\_5.6\Engine\Source\Programs\AutomationTool\Gauntlet\Gauntlet.Automation.csproj) and change `<WarningsNotAsErrors>612,618</WarningsNotAsErrors>`, to `<WarningsNotAsErrors>612,618,1901,1902,1903</WarningsNotAsErrors>`

or

`<TreatWarningsAsErrors>true</TreatWarningsAsErrors>`

to

`<TreatWarningsAsErrors>false</TreatWarningsAsErrors>`

Yeah, I was thinking about this, but why this appeared, and is there a way to fix the thing that causes warnings, maybe?

this is a known issue, there’s a couple of posts in the forum addressing this.

this is addressed by epic on 5.6.1. you can see it on the github.

if you have a source copy of the engine, you would want to pull the changes.

i would have thought that obtaining 5.6.1 from the installer would fix it.

I am currently on 5.6.1; maybe it will be fixed in the next release, I will check that.
