Asking on behalf of a friend.

He maintain separate lists of email addresses on the computer in a plain text file. Depending upon the content, he pastes specific list/s into the TO/CC/BCC field.
Over the past week, or thereabouts -July 2022- gmail will not paste addresses into the to/cc/bcc field. Until that date, everything was peachy. Now, only the first email address from the clipboard is reproduced in the chosen to/cc/bcc field. All other addresses - still in the clipboard - are discarded by gmail.
How should all email addresses in the clipboard be pasted into the relevant to/cc/bcc field of the email?
