One campaign running successfully another not running

Your software
My Mautic version is: 2.15
My PHP version is: 7.2

Your problem
My problem is:
I have a campaign that has been running fine for three months. I designed a new campaign two days ago and it won’t fire! Within the three months I upgraded my php to 7.2 and while I recently noticed that Cron was sending out emails to admin that ea-70 directory was not found, the old campaign continued to run!
I renamed the path to ea-72
In my new campaign, no contacts appear in …/campaigns/view/xx although the segments are all ok.
These errors are showing in the log:
Nothing related to email or the campaign appeared in any log
Steps I have tried to fix the problem:
I sent test emails successfully. SMTP connection is good. Created a new campaign and added the contacts manually, emails are not triggered.

Seems like your upgrade of PHP is the underlying issue here. A simple restart of Apache may solve it if you’ve done everything else correctly. Just retrace your steps.

after doing that if the problem persists: In ssh run php -v and verify your php version is correct.
Also verify you have php-imap installed. For reference—>
