  Since upgrading from v11 to v18, I’m getting random NullReferenceExceptions in the “EndInit()” of the SectionReport.

  . I’ve tried moving things around beforehand, changing the default GDI+ to CrossPlatform, but nothing has helped. It’s essentially unusable. HELP!!

  It also occurs sometimes in the Sections.Add(…) in the designer.

  Here’s the end of the stack trace:

  2025-03-27 07:53:47 System.NullReferenceException: Object reference not set to an instance of an object. (source: System) [ at System.ComponentModel.TypeDescriptor.GetPropertiesImpl(Object component, Attribute attributes, Boolean noCustomTypeDesc, Boolean noAttributes)

  I believe this is now solved. It appears I had some “side” DLLs like System.Memory.dll, System.Buffers.dll, etc… that were not consistent across all of my projects and ActiveReports was running with some older DLLs than it should have.
