System page 500 on managed hosts: the System endpoint called disk_free_space() / disk_total_space() unguarded — hosts like Kinsta remove them from the web PHP via disable_functions, which turns the call into a fatal error (@ doesn't save you, and the CLI on the same box reports nothing disabled). Both are now function_exists()-guarded, as is php_uname() a few lines below — the next fatal waiting on hardened hosts. Disk usage degrades to "Unknown" where the host hides it.
