I got 'MSB3191' error code from building up SteamworksExample

Hi all,

After I extracted steamworks_sdk file then open it up to build.
Error!???

note: I edit nothing in project properties

Which version are you trying to build?. I know 1.54 had this issue and I usually suggest 1.53 as it is the easiest to build without complications, using studio 2019 at least.
