sorry, did you solve this problem?
i got the error because my excel has the some pivot table, and i click [refresh the data when opening the file], the pivot table overlap another pivot table,
and i need to read lots of excls one by one, some of them, build by excel macro, that means the excels have full of blank cells, so excel scope can not finish reading data in right time.
and any when you open excel by hand, some time you can see the Error message, in fact when it appeared, uipath got the error too.
I know this response is late but here is my experience for anyone who might encounter something similar in the near or distant future. Restarting the computer when this error appears seems to do the trick for me. Unfortunately, i am having to do this each time this error occurs. Hoping for a more permanent solution as this issue only started when i started playing around with .xlsm files.
Same thing is happening with me also.
My Bot was working fine but now getting the issue.
The exception is : Call was rejected by callee. (0x80010001 (RPC_E_CALL_REJECTED)) at Source: Unhide - Booking Rates
For one of the sheet.
