*Steps to reproduce:*
# Ensure IL2CPP module is installed in your editor.
# Create a new 2D URP project, import [Lost Crypt.|https://assetstore.unity.com/packages/essentials/tutorial-projects/lost-crypt-2d-sample-project-158673?srsltid=AfmBOorfiWUg9F5z7rGJomGShHrcho96MAqzzSVZm8aYXmNuolXENBpm]
# Build & Run.

*Actual results:* Error appears:
{code:java}
Assets\Settings\SpritePostProcessor.cs(4,36): error CS0246: The type or namespace name 'AssetPostprocessor' could not be found (are you missing a using directive or an assembly reference?){code}
 Can't copy more details, domain reloads and clears the console before it is possible. (UUM-91487)

*Expected results:* Build has no issues.

*Reproducible with versions:* 6000.1.0a9, 6000.0.30f1

*Not reproducible with versions:* 2022.3.54f1

*Tested on (OS):* Win 10 primarily, also confirmed on Win 11

*Notes:*
* Build and run was done on the Windows platform.
* Due to this likely being that the project needs updating for U6 rather than an engine bug, I did not extensively regression test this issue. However, if the FAV is useful, please contact ticket reporter.
