For the second error, contact your sysadmin or host and ask them to enable the proc_open function.

If they are unable to, you will have to switch to using SMTP for email delivery.

The headers already sent error could be a corrupt file - run the file health check to confirm.

Th proc_open error is self explanatory (and has been posted about numerous times).
Enable the function or use SMTP.

file checked and all good but still the error is there and keeps coming.

What would recommend to be done to have this issue solved?

Are you running a unmodified default style with no addons running since this is a new upgrade?

yes

Well then IMO your best bet is to submit a ticket, that way a dev can look into it first hand in the site.
