-ArgumentOutOfRangeException errors are thrown on undoing after changing resolution value in HDRP Compositor.
-Game view window appears black with ArgumentOutOfRangeException throwing continuously.
-Workaround: Restart the editor.

Steps to repro:
1. Create a new HDRP template project
2. Windows > Render Pipeline > HD Render Pipeline Compositor.
3. Enable Compositor > Render Schedule > Base Layer.
4. Properties > AOVS > Albedo.
5. Properties > AOVS > None.
6. Press CTRL+Z.

Actual Result:
ArgumentOutOfRangeException errors are thrown in the console.

Expected Result:
No errors in the console.

Reproducible in:
2020.2.0a19, 2020.1.0f1, 2020.1.0b13 with Package version 9.0.0 preview.33.

Note: HDRP Compositor window introduced in 9.0.0 preview.33.

Environment:
Occurring on Windows 10 & Mac 10.15.
