I first saw this exception for a custom add-in that I had created an installed on my computer. I un-registered all addins in C:\ProgramData\Autodesk\Revit\Addins\2023 and C:\Program Files\Autodesk\Revit 2023\AddIns
Then the error happened for C:\Program Files\Autodesk\Revit 2023\SDA\bin\ICSharpCode.Core.WinForms.dll
