Microsoft Access closes when I try to delete data in a field and refresh. How can I delete the data?

When I delete data in a field in Microsoft Access and refresh, the application closes. It only happens with the one specific field "Vendor_Custom_Fields_Nots" from the APM_MASTER_VENDOR_CUSTOM_FIELDS table. I accidentally entered data in a field and now I'm trying to delete it. I tried to do an update query, but that closed on me too.
