How to Prevent “Transaction is already closed” Error When Importing CSV?

[etyb2025]

I have a question.When importing a CSV file, if the user clicks “OK” and performs other actions before the upload is complete, the upload still succeeds, but an error message appears: “Action failed: Transaction is already closed.”

Would it be possible to either disable the “OK” button until the upload is complete or prevent the “Transaction is already closed” message from appearing? Thank you in advance for your assistance!
