Every time when I open my project or create a new one I have 436 bugs on my console and every one of them says:
Library\PackageCache\com.unity.test-framework@1.1.19\UnityEngine.TestRunner\Utils\AssemblyProvider\PlayerTestAssemblyProvider.cs(24,16): error CS0246: The type or namespace name '’ could not be found (are you missing a using directive or an assembly reference?)
In place of "" there is the other word in every bug. Do you guys have or had a problem like that? Could you help me, please?
