Downgrading is not supported in general, so errors are expected. In this specific case, removing the Visual Effect Graph package and adding it again through the Package Manager fixes the errors.

How to reproduce:
1. Open and close the attached project “DowngradeBugFinal.zip“
2. Open the project again, but in the previous Unity stream or downgrade the an older version of the same stream

Expected result: No error in the Console
Actual result: Error in the Console

Reproducible with: 2020.3.47f1, 2021.3.22f1, 2022.2.13f1, 2023.1.0b11, 2023.2.0a9

Reproduced on: macOS 13.2.1 (Intel)

Note: Sometimes you need to downgrade more than one version when downgrading to an older version of the same stream to reproduce the issue
