Bug GetFloat and AddSubTextObject rrrors when usign TextMeshPro

We have issue in our project with TextMeshPro in combination with Addressables. We moved all fonts and materials to addressables and removed them from resource folder. Since then we started getting errors when using Material tag in our texts. Visually text doesn't appear at all until user restarts the game.
Error stack for GetFloat error. It doesn't happen all the time, only sometimes and besides that everything works well.

Code (CSharp):

1. Non-fatal Exception: NullReferenceException
2. 0  ???                            0x0 get_name + 194 (UnityEngineObject.bindings.cs:194)

14. 12 ???                            0x0 ScrollRect:LateUpdate (UnityEngine.UI)

We are using newest TextMeshPro + Unity 2022.1.13

This is how we load materials when game starts

Code (CSharp):

1. var fontMaterials = Addressables.LoadAssetsAsync<Material>("FontMaterial", null);
2.         asyncOperationHandles.Add(fontMaterials);
3.  
4.         fontMaterials.Completed += fonts =>
5.         {
6.             logger.Log($"[Materials] Found {fonts.Result.Count} materials");
7.             foreach (var material in fonts.Result)
8.             {
9.                 int materialHashCode = TMP_TextUtilities.GetHashCode(material.name);
10.  
11.                 if(!MaterialReferenceManager.TryGetMaterial(materialHashCode, out Material tempMaterial))
12.                 {
13.                     MaterialReferenceManager.AddFontMaterial(materialHashCode, material);
14.                     logger.Log($"[Materials] Added {material.name} material");
15.                 }
16.             }
17.         };

Any help solving this issue?

 

Any insight on this issue? @Stephan_B

 

Bump

 

Any chance you could submit a bug report with project or scene that would enable me to reproduce / take a closer look?

You could also provide me with an exported scene via PM if that is easier.

 

Of course, let me create a scene. I will send it in private message
