Just in case you are running into this problem, there is a workaround that a user posted in the following link.
https://github.com/Unity-Technologies/PostProcessing/issues/793
Which basically is, by adding the following function to RuntimeUtilities.cs in post-processing stack package.
public static void ResetResources()
{
s_CopyStdMaterial = null;
s_CopySheet = null;
s_CopyMaterial = null;
s_CopyFromTexArrayMaterial = null;
s_CopyStdFromDoubleWideMaterial = null;
s_CopySheet = null;
s_CopyFromTexArraySheet = null;
}
Then you should run this function in PostProcessLayer.cs as you can see in the following snippet code.
void SetupContext(PostProcessRenderContext context)
{
RuntimeUtilities.s_Resources = m_Resources;
RuntimeUtilities.ResetResources();
