Output Tool : Invalid state to read file ERROR

[JunePark]

Hi, I'm having errors with the output tool(maybe it was due to the 2020.3 update on September 1st).

Error Name : 'Invalid state to read file'

I've found out that the error appears only when if there is a file that already exists(ex. FS2.xlsx on the capture below).

If I delete the file FS2.xlsx then run the workflow, the output tool works well.

Just updated to the 2020.3 (Corporate policy in my company didn´t released the 2020.4 yet) and I'm having the same issue.

Changed the excel output component to the "excel legacy -> delete data and append" and it's working, however costs a lot of performance, same workflow is taking a lot time more to finish the proccess.

Not the best option, but since I cannot just update to the 2020.4 so far, it will work.
