Can anyone help me fix this errors i got after updating Unity?

I started the 2D Game Kit at Unity Learn in 2019.3.3.f1 version of Unity. After updating to the new (2019.3.6.f1) version today, and opening the project i saved last night, I got the error list from the image.
Does anyone know how i can fix this? I’m new to Unity and don’t have any experience with updating Unity versions or re-importing projects.
Thanks in advance!
