sf.filemanager is undefined

Hello, after I updated to latest version ( 18.0.4.32) I started getting the following error in a specific page. After some digging I found out that it's because I have the Gantt chart component in the page. How are the two things related and is there fix ?

 Error: Microsoft.JSInterop.JSException: sf.filemanager is undefined

Hello, after upgrade I still get this error ocassionally. Is there anything else that can interfere the execution and cause this problem ?

Edit: I even get this error on your demo. Please note that its not guarantee that it will happen. If you refresh the page the bug could appear. Attaching image from the demo

Hi Georgi, 
 
We have analyzed your query. But the reported problem were not reproduced in 18.4.33 version. The reported problem is may arises due to nuget cache. So kindly follow the below documentation guidelines for updating packages and ensure.
