Try this option

Just add ?Contents=1 after your URL and Close the web part and it should work.

HI 

I got below error in that webpart.

I got below logs message sharepoint log investigation tool.

Let us know any suggestions on this.

I would suggest that you try these two options:

1. reindex that list only.

2. Create a custom view with the required columns and then apply that view on your list view webpart.
