TextMesh Pro Assertion failed on expression: 'ins.second || ins.first->second == targetHash || (ins.first->second

Hi,

I get the following assert in 2020.1.8f1:

Code (CSharp):

1. Assertion failed on expression: 'ins.second || ins.first->second == targetHash || (ins.first->second == CircularDependencyHash() && !targetHash.IsValid()) || GetPathFromAssetGuidV2(key.GetGUID()).ends_with(".cs")'
2. UnityEditor.AssetDatabase:LoadAssetAtPath(String, Type)
3. TMPro.EditorUtilities.TMPro_TexturePostProcessor:OnPostprocessTexture(Texture2D) (at Library/PackageCache/com.unity.textmeshpro@3.0.1/Scripts/Editor/TMPro_TexturePostProcessor.cs:14)
4. UnityEditor.AssetPostprocessingInternal:PostprocessTexture(Texture2D, String)
5.  

What does it mean and what should I do about it?

 

Are you getting this error while creating a build?

What are the steps to reproduce this error?

 

I got this error in editor.
I've downloaded some changes from our version control, so I assume some assets are changed.
I'll see if it reproduces going back to an older version and downloading again.

 

See the following post which includes a solution for that issue.

The code changes contained in that post will be included in the next release of the TMP package.
