A bunch of errors just showed up after opening the project (2020.1.4f1)
Hello, Everything was fine yesterday when I was working on my project. Today when I opened it up I encountered 36 fatal errors that I have no idea where they came from nor what to do to fix them. These errors vary from Artifacts corrupted and "type or namespace could not be found", both in the Editor folder and the project itself (PackageManager and PackageCache). If someone could help me, I would appreciate it greatly. It's really pissing me off.
7 Errors just like this one: Failed to load 'C:/Users/luism/Desktop/Unitygame/Beat/Library/Artifacts/e3/e3760e0f5a2aa9e3e9a5208246d5a7a9'. File may be corrupted or was serialized with a newer version of Unity.
6 Errors from this folder: Library\PackageCache\com.unity.test-framework@1.1.16\UnityEditor.TestRunner\CommandLineTest\RunData.cs(6,16): error CS0246: The type or namespace name 'ExecutionSettings' could not be found (are you missing a using directive or an assembly reference?)
23 Errors like this one: C:\Program Files\Unity\Hub\Editor\2020.1.4f1\Editor\Data\Resources\PackageManager\BuiltInPackages\com.unity.ugui\Runtime\UI\Core\Layout\AspectRatioFitter.cs(12,51): error CS0246: The type or namespace name 'ILayoutSelfController' could not be found (are you missing a using directive or an assembly reference?)
This last one is related to UI, and my UI in the project lost it's default script refferences and is displayed with a huge red X in the scene view.
