I'm from Cloudways Magento Community

Need to reproduce the steps for resolving the issue:

Downgrade your PHP version and check if its works
It seems some of your extensions create conflict in it, so what you can do is launch another application with the latest version and deploy each of your extensions one by one. This will let you know what causes the conflicts.
Check file permissions: https://support.cloudways.com/en/articles/5126387-how-can-i-reset-file-and-folder-permissions
Check the class which has a readonly keyword because: readonly is a reserved keyword in PHP 8.1. Any existing classes or other symbols that use the name readonly (case insensitive) will result in a syntax error in PHP 8.1.

It is not possible to port the readonly functionality to older PHP versions. However, the @readonly / @property-read annotations is understood by static analyzers such as Psalm.

Thanks
