Error when uploading contacts

I have been uploading contact lists for years without issue, but today, I am receiving the following message "An error occurred while attempting to save your changes. To continue, please try again".

I have checked - there are no missing email addresses, no duplicate email addresses, and I have tried uploading .csv and .xlsx files multiple times with no success.

Is anyone else having issues? Or do you have any suggestions?
