You can try refreshing the page or closing and reopening your browser. If that doesn't work clear the browser cache or use a different browser to access the settings. You may also want to try a safe mode or incognito tab to bypass the crash issue and adjust the per page setting back to a lower number. For more information visit this website.
It looks like setting the "per page" value to 999 overloaded the system, causing the page to crash. There are some ways to solve it. If you have database or server access, manually reset the "per page" value to a lower number. Clear your browser's cache/cookies, or use a different browser/device to try loading the page.
Hope this helps!

It seems that changing the "per page" setting to 999 is causing the page to crash due to excessive data loading. To fix this, try clearing your browser cache and cookies or access the settings via a different browser or in incognito mode. If that doesn’t work, you may need to manually reset the setting by editing the database or using an admin tool, if available. Alternatively, contact your hosting provider for assistance.
