Wordpress Update Conflict with Ultimate Affiliate Pro Plugin

I was working on my affiliate program. Then I lost the affiliate account page and now, get an email that states there are issues from my host. I am pasting that info below. I have tried to send a support ticket, but it goes to an error page.

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Indeed Ultimate Affiliate Pro.

First, visit your website (https://homeschoolcouponbook.com/) and check for any visible issues. Next, visit the page where the error was caught (https://homeschoolcouponbook.com/wp-admin/admin-ajax.php) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.

To keep your site safe, this link will expire in 1 day. Don’t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.6
Current theme: Refined Theme (version 1.0.1)
Current plugin: Indeed Ultimate Affiliate Pro (version 6.8)
PHP version 7.4.13
