Hi Tarika,
Based on your description, I tested your issue in my own environment. I worked fine without any error messages as shown in the following figure. (My sample data is very simple.)
I suggest you provide the steps of import Excel data to the Access table, and tell me the Date format in the Excel file.
Then you can refer to this link and try to use Advanced button to import data:

If possible you can create a sample of Excel file and send it to our email address:

Note: Please add the URL of the case in the email subject or body.
I'm glad to help and follow up your reply.
