-Editor crashes while compiling URP/Lit shader after switching Graphics APIs to OpenGLES3.
-After the crash When opening the project again, it crashes immediately.

Steps to repro:
1. Create a new URP template project.
2. File > Build Settings > Player Settings > Other Settings.
3. Uncheck Auto Graphics API for Windows checkbox.
4. Add OpenGLES3 > Drag to the top of the list.
5. Restart the editor > Wait for GI bake.

Actual Result:
Editor crashes while compiling Universal Lit shader.

Expected Result:
GI bake successfully without editor crash.

Reproducible in:
2020.2.0a16, 2020.2.0a11 with Package Version: 9.0.0, 8.1.0.

Working Fine in:
2020.2.0a10, 2020.1.0b14 with Package Version: 9.0.0, 8.1.0.

Environment:
Occurring only on Windows.
