There are very little chances of a PHP update breaking your WordPress site. However, with the abundance of free and paid plugins, a single line of poor code can result into an error.
The first thing you need to do is make sure that it is not a plugin or theme causing this error. To do that deactivate all your WordPress plugins and switch to a default WordPress theme.
If this does not solve your issue, then contact your web host’s support team. There is a good chance that the issue you are facing will already be in their notice, and they will be able to assist you.
If your web host is unable to help you out, then try to install a fresh copy of WordPress and then restore your WordPress site from backup.
