Hello,
My opera mail has gone berserk.
will not download most emails, some are downloaded multiple times every time I open the email program, no matter how many times I delete them.

Checking for updates of the email program returns an error message ,as well as sending an email after a crash.

I have used Opera mail for many years without issue, nothing has changed that I am aware of to cause any problem. I am using to check 2 pop accounts which are operating normally, Win 10.
