title: Unity Error: Feature 'out variable declaration'
body: <p>I copied a project from one computer to another, however, when I started Unity I got tons of errors all saying practically the same thing.</p>
  
  <p>Researched online and found nothing. Project worked perfectly fine on a different computer before I moved it.</p>
  
  <p><code>D:/Unity Games/UYW/Library/PackageCache/com.unity.textmeshpro@2.0.0/Scripts/Runtime/TMPro_UGUI_Private.cs(2028,130): error CS1644: Feature `out variable declaration' cannot be used because it is not part of the C# 4.0 language specification</code></p>
  
  <p>Shouldn't give any errors.</p>
