Issue Sudden problem with Amazon Lightsail PLESK instance.

Server operating system version

Ubuntu 18.0.4

Plesk version and microupdate number

18.0.20

Ubuntu 18.04 with Plesk 18.0.20 on Amazon Lightsail instance

1. I am a Linux beginner, and I have been running PLESK Lightsail instance for 2 years for my organisation's website running WordPress.
2. On Friday the CPU utilisation suddenly constantly exceeded the sustainable zone. When looking at the TOP command processes, I saw that the PHP & php-fpm are taking almost 100% CPU. They are not reduced even when I closed ports 80 and 443. I have tried to stop apache and nginx too, but the PHP and php-fpm were still running.
3. Curiously, the website is still running and accessible.
4. I also can't login to PLESK, receiving this message after I click submit button:

Server Error 500 Error Class 'PleskExt\Monitoring\Helper\CloudMonitoring' not found​

Type Error Message Class 'PleskExt\Monitoring\Helper\CloudMonitoring' not found File CustomButtons.php Line 49​

I tried to use PLESK repair utility but it doesn't seem helping much, after I enter command "plesk repair all -y" the screen just freeze and I can't do anything with the terminal.​

Additionally, I also got this:
/dev/xvda1 on / 574.49 GB of 620.35 GB total
/dev/loop0 on /snap/amazon-ssm-agent/5656 0.00 B of 25.13 MB total

/dev/loop5 on /snap/core18/2566 0.00 B of 55.63 MB total

Any idea what is the problem in my server? Any additional info do you need me to give you so you can advise me what I should do?

Thanks,
VS

Looks like this case: Issue - Composer dependencies require on Plesk

Might be!

Thanks IgorG, I'll try this.
