I don’t know what issue you have - you only said you “have similar issue”. But you mention VirtualScroll, which didn’t appear before in this topic at all.

Do you get the same error message as the original topic creator?
What is your error message?

If you don’t have the same problem, please create a new topic and add all your information to it.
