AFO An Exception Error

Hi Expert,

Could you please help me to get an idea about this issue.

Steps:

1. open AFO and connect to plaform and create a report base on BEx query.
2. alter the default layout.
3. save it as xlsx file.(Not sure this is allowed)
4. now close all the AFO application.
5. Now try to open the saved xlsx file to refresh the data.
6. the excel went into not responding stage.
7. after 12min we killed the applicaiton service via task manager and got the below error.

could you please suggest whether the step I have follwed is an allowed one or we need to do something to fix thes kind of issue in AFO.

Note:

BI 4.1 SP05

AFO 2.1

Thanks!

Regards,
