Getting errors every now and then with 9.5.2 and dtge 9.0.2, though think it's still in v10.0.1 too.

Think it's this line?? https://github.com/skttl/umbraco-doc-type-grid-editor/blob/dev-v10/src/Our.Umbraco.DocTypeGridEditor/Helpers/DocTypeGridEditorHelper.cs#L252

Subject: We’ve detected that threads are mixing synchronous code with asynchronous code

Review recommendations to avoid deadlocks.

We’ve detected that threads are mixing synchronous code with asynchronous code
Azure App Service has identified that 150 threads may be mixing synchronous code with asynchronous code. Application code is calling Task. Result and is synchronously waiting on the Task object, which can lead to deadlocks in the process.
The function calling Task.Result is Our.Umbraco.DocTypeGridEditor.Helpers.DocTypeGridEditorHelper.RenderDocTypeGridEditorItem(Microsoft.AspNetCore.Mvc.IViewComponentHelper, Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper, Umbraco.Cms.Core.Models.PublishedContent.IPublishedElement, System.String, System.String, System.String, Boolean), but the entire thread's call stack should be reviewed to identify the blocking pattern. Please review the call stack closely and make sure that your code is using the C# await keyword.
