Error -2147417848 Automation error The object invoked has disconnected from its clients

Question

I am working on clearing some tables in 3 excel sheets.

My code was working fine with Excel 2007, as i switched to excel 2010 i started getting this runtime error Automation error The object invoked has disconnected from its clients, error number -2147417848 and then excel freezes.

the error is showing after running this function 2 times on the line

    Sheets("Risk Details").Range("A3" & ":BV" & (count + 1)).Delete Shift:=xlUp

can anyone help me in finding out why this is happening and how to work around it?

below are the full code for the function

Microsoft provide a high-level answer:

If the code always appears to work the first time that it is run, and if the errors or the unexpected behaviors occur only during subsequent calls to the same code, an unqualified method call is the cause.
