ErrorMessage: Error displaying dialog: The current process uses all handles the maximum allowed number ofWindow Manager objects.

Hey community,

i'm having following problem.

We have developed an automatic pipeline to transform out maya models and fbx files into unity assetbundles. Now, we want to add the feature to this pipeline to export our created assets as .unitypackage.

When we are calling the AssetDatabase.ExportPackage()-Method, the export process is getting the already mentioned error. "ErrorMessage: Error dsplaying dialog: The current process uses all handles the maximum allowed number ofWindow Manager objects." (had to translate this error message, sorry about that)

How could this issue be fixed so that our export pipeline works correctly and creates the assetbundles and then the corresponding unity-package? Is it possible that theirs a memory leak when drawing the exporting windows where their handles arent Destroyed/Disposed correctly after the BuildPipeline.BuildAssetBundles()-Method was executed?
