The error message you are seeing suggests that there is an issue with the taxes associated with the invoice and the credit note. Specifically, it seems that the taxes may have been modified since the creation of the journal entry, which is causing the error message to appear.

To resolve this issue, you can follow these steps:

Review the taxes associated with the invoice and the credit note: Take a closer look at the taxes associated with both the invoice and the credit note. Make sure that the tax rates and configurations are correct and consistent across both documents.

Verify that the taxes have not been modified: If there have been any changes made to the taxes associated with the invoice after the journal entry has been created, this could cause issues when creating a credit note. Verify that the taxes have not been modified since the creation of the journal entry.

Create the credit note manually: If the taxes have been modified or if you are unable to identify the root cause of the issue, you may need to create the credit note manually. This will involve creating a new journal entry to account for the credit note, and manually entering all of the necessary information, including the correct tax rates and configurations.

Verify the tax amounts: Once you have created the credit note manually, double-check that the tax amounts are correct and consistent with the original invoice. This will ensure that your records are accurate and up-to-date.

By following these steps, you should be able to resolve the issue with the tax error when creating a credit note from an invoice.
