Unable load test suite

Hello guys,
I have some problem. I can’t open my test suite suddenly.
Here the image when I open the test suite

I’m using katalon studio version5.10.1. Can someone help me about this?
Thank you

@dewikm411, please send us the log file. You can find it under Help > Error Log.

Here the error log

@dewikm411, Do you have any report which is named differently, i.e, not in the default timestamp format generated by Katalon Studio? If so, please back it up and delete the report from Report folder, then try again to see if the test suite is opened successfully.

@huynguyen Thankyou. It works now. Btw if like that, it means we can’t rename the report?
