Excel activity crashes UIPath

Intermitently facing an error where UIPath gets crashed. Same code was working fine before.
One crash instant logger was due to invalid cast exception, while reading Data range.
Other crash instance was during write, we have not captured its exception.
Due to above UIPath gets terminated, even though code is inside try catch.
Excel workbook is closed everytime, even we have killed Process for same.
Please suggest solution for same.

Check the tabs to ensure the worksheet used range are not huge as this sometimes causes memory issues and terminates it rather than throwing an exception.

Thanks for prompt response.
Last column is CU
Last row number is 2
I dont think it may be due to high size as file size is 880kb
