Stop loading the user from child site

I just made a mistake that choosing a child site which has 40,000 users.
How could I stop this loading?

Hi @dixonchan1994

Welcome to the MainWP Community!

You can refresh the page to stop the process.

Additionally, any process will naturally timeout due to PHP Max Execution Time or cURL Timeout server settings, which are usually set to somewhere between 60 seconds and several minutes.
