Reproduction steps:
1. Open project “IN - 26766”
2. Open scene “KeepFrame”
3. Enter Play Mode

Expected result: no errors are thrown and the particles in the scene have a smudged trail effect
Actual result: errors are thrown in the console and particles have no effect - the custom renderer feature doesn’t work

Reproducible with: 2022.1.0b1, 2022.2.3f1
Not reproducible with: 2021.3.16f1, 2022.1.0a16
Couldn’t test with: 2020.3.44f1 (no samples available), 2023.1.0a26 (due to compiler errors trying to import samples)

Reproducible on: macOS Catalina 10.15.7 (Intel)

Notes:
- The attached project uses official URP samples imported through Package Manager
- The “TrailEffect” sample scene also doesn’t work as expected (errors are thrown in the console and the trail effect isn’t visible) due to the same custom renderer feature from “KeepFrame” being used
- Couldn’t build player due to compiler errors
