Dispose Error When Using ExRuntime.dll to Create Separate UI in WinForms

Hello,

I am working on a WinForms project utilizing ExRuntime.dll.
My goal is to create a separate UI that allows users to open sheets or modify data in EB even when the Assistant is running.

I have managed to achieve a partially separated state using frm.Show(myApplication.ActiveWindowWinforms) as shown in the attached image. However, I encounter a Dispose error when closing or restarting the application.

I would deeply appreciate any guidance or assistance from someone who can help me resolve this issue.

Thank you in advance!
