Regression

Yes

The Game view freezes and error "InvalidOperationException: Trying to use a texture (_AdditionalLightsShadowmapTexture) that was already released or not yet created" thrown when MSAA and is enabled with Forward rendering path

--

-

How to reproduce:
1. Create a project with URP 3D sample
2. Open the “GardenScene“
3. Open the “Assets>Settings>PC>PC_High_Renderer.asset“ in the Inspector
4. Set rendering path to Forward
5. Enter the Play Mode
6. Open the “Assets>Settings>PC>PC_High.asset“ in the Inspector
7. Set Anti Aliasing (MSAA) to 2x
8. Observe the Game view

Expected result: No errors are thrown and the Game view does not freeze
Actual result: “InvalidOperationException: Trying to use a texture (_AdditionalLightsShadowmapTexture) that was already released or not yet created“ errors thrown and the Game view freezes

Reproducible with: 6000.0.2f1
Not reproducible with: 2021.3.38f1, 2022.3.29f1

Reproducible on: macOS 13.5.2 (Intel), Windows 10 Pro
Not reproducible on: No other environments tested

Notes:
- Setting the rendering path to Deferred (or disabling Depth Priming Mode) fixes the issue
- The issue happens with MSAA set to 2x, 4x and 8x
- The issue happens with the URP 3D Sample
- Downgrading/upgrading the URP 3D Sample project where the issue was not reproducible to a reproducible with version will make the issue not reproduce. The issue is probably in the makings of the sample
