If you see the event log , you can find that the issues is catched in SSRS event handler- Microsoft.ReportingServices.SharePoint.UI.ItemEventHandler ,  I guess SSRS Query is throwing error that are catched in Event Handler.

I think you should test whether this is SQL query/SP problem or not , by changing your Query to simple one table query remove all join /multi table references.

You can return hard coded value for other table fields, so your report will not raise any binding error , something like this e.g. B and C are columns from other table in your join-

Select A, 'val1' as B, 'val2' as C
From Table1

HI,The issue could be of below reasons.

         The custom event receiver assembly cannot be found, or it is corrupted.
         The SharePoint Server 2010 assembly cannot be found, or it is corrupted.

Please check the link below that provides more information on this.
