Dynamo player cause Excel file corrupt when reading multiple files

Greeting.

I try to read data from two excel files by using Import.Excel OTB node.
Things work within expectation when run it through Dynamo editor.

But when I try to run it with Dynamo player. Some how one of the Excel file got corrupt after a single run, the dialogue said ‘file format does not match’. It seems try to open Excel and freeze, although the parameter which control showing the file has been set to false.

When I try to run it through the Dynamo editor there seems to be no trouble at all. I am total clueless about what went wrong

Excel comes with Office 365 and our team could only use Revit 2022 due to client requirement, thus Dynamo version has be restrict to 2.12 for both Core and Revit.

Thanks for help and advice in advance.

Can you show how you’re using the excel nodes? Can only guess at the possible source of the issue without seeing the setup.

Also, are both excel files on the local disc, or is there some form of web mirroring involved?

If you can use them, the open xml excel nodes would be a good test.
