How to reproduce:
1. Open the attached "SelectDependencies" project in Unity 2019.4.15f1
2. When the "Asset Database Version Upgrade" window appears select the "No" option
3. In the Project window right-click on the "WaitForServerResponseAnim" Asset and select the "Select Dependencies" option

Expected results: No errors are thrown
Actual results: The "ArgumentException: Asset path cannot be null or empty." error is thrown

Reproducible with: 2019.3.0b10, 2019.4.15f1
Could not test with: 2018.4.29f1 because the Asset Database v2 is not yet introduced, 2019.3.0b9, 2020.1.14f1, 2020.2.0b11, 2021.1.0a6 because the Asset Database v2 is used automatically without any choice to use the v1

Notes:
- The Animation has to have the "Image.color" property animated to reproduce the issue
- The issue is only reproducible on versions that have the "Asset Database Version Upgrade" window appear when opening a project that was last saved in Asset Database v1 and choosing not to upgrade to the Asset Database v2
- Choosing to use the Asset Database v2 will not make the issue appear
- Right-click on any Asset and choosing the "Reimporting all" option fixes the issue but reimporting only the animation does not
