The issue you are facing:

Opening /index.php/settings/admin/serverinfo throws Internal Server Error.
Problem exists since a while and over several Nextcloud versions

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Opening /index.php/settings/admin/serverinfo

I found this issue for you.

Perhaps you can modify something in this code (lib/PhpStatistics.php)

	public function getPhpStatistics(): array {
		return [
			'version' => PHP_MAJOR_VERSION . '.' . PHP_MINOR_VERSION . '.' . PHP_RELEASE_VERSION,
			'memory_limit' => $this->phpIni->getBytes('memory_limit'),
			'max_execution_time' => $this->phpIni->getNumeric('max_execution_time'),
			'upload_max_filesize' => $this->phpIni->getBytes('upload_max_filesize'),
			'opcache' => $this->getOPcacheStatus(),
			'apcu' => $this->getAPCuStatus(),
		];
	}

'opcache' => [],
