"InvalidOperationException: Trying to use a texture (_MainLightShadowmapTexture)..." and other Render Graph errors when MSAA is enabled with Render Graph and Game view tab is active
Reproduction steps:
1. Open the attached “IN-97125.zip” project
2. Open the “Main” Scene (Assets > _Project > Scenes)
3. Make sure the Game view tab is active
4. Observe the Console
Expected result: No errors
Actual result: “Render Graph Execution error” and “InvalidOperationException: Trying to use a texture (_MainLightShadowmapTexture) that was already released or not yet created.” errors
Reproducible with: 6000.0.43f1, 6000.1.0b11, 6000.2.0a7
Couldn’t test with: 2022.3.60f1 (Render Graph not supported)
Reproducible on: Windows 10, Windows 11
Not reproducible on: no other environment tested
Notes:
- Disabling the Anti Aliasing (MSAA) on the “URP-Default.asset” makes the issue not reproduce anymore
- Disabling the “Directional Light” GameObject makes “InvalidOperationException: Trying to use a texture (_InternalGradingLut) that was already released or not yet created.” error appear instead

Resolution Note:
This is actually working as designed. You just need to use an unsafe pass instead of a raster pass to be able to use a texture with MSAA with a texture with no MSAA in the same pass :)
You might encounter another issue with imported textures, but a fix for that is in an upcoming version so make sure to update your project to the latest unity!
