COM object that has been separated from its underlying RCW cannot be used. - excel

I have a problem with “write cell” activity in excell.
The process that has been using it has been in stable condition for some time, but from time to time (once every 10 days) the following error occurs:

“COM object that has been separated from its underlying RCW cannot be used.” At this step, the process stops performing and does not write the appropriate value to the field.
When I try to start the process manually, all steps are done as expected. So there are no rules when an error occurs, and it’s impossible to conclude if it depends on any other activity.

Does anyone have an idea why is this happening?

@Olivera_Kalinic ,
are you using excel activity or workbook activity?
if you are using excel activity (Write cell ) to write to cell please try using workbook activity

else try vice versa. To my knowledge this issue is due to duplication/corruption of excel instance

Good day
cheers

Why does that duplication happen?

@Olivera_Kalinic
I mean the duplication or corruption ! , try with other activity

That can’t be an option because of wrong inserting decimal numbers when using workbook activity.
Are there any other options?
