How to reproduce:
1. Create a new Unity 2019.3.0b6 HDRP Project
2. Open Package Manager and update High Definition RP package to 7.1.2
3. Observe the console

Expected result: no errors in the console
Actual result: "System.Exception: Cannot load. Incorrect path:" and "Read only asset has no meta file" errors appear in the console

Reproduced in: 2019.3.0b6, 2020.1.0a8
Can not reproduce in: 2017.4.33f1 (no HDRP), 2018.4.11f1. 2019.2.8f1 (7.1.2 update not available)

Notes:
- Reproducible on any Unity version that has HDRP 7.1.2 update available (see https://fogbugz.unity3d.com/f/cases/edit/1198753/ as some Unity version will not be compatible with 7.1.2
- Workaround is to restart Unity, which will cause either no errors in the console or clearable errors
