For RHEL operating system:
Connect to the Plesk server via SSH.
Update system packages:
# yum update -y
Reboot the server.
Note: if reboot via SSH does not work, reboot the server from your service provider panel (AWS, GCP, Hetzner Robot, etc.).
For CentOS/Debian/Ubuntu-based distributions the bug fix is yet to be implemented. Contact the operating system vendor for further assistance.
