instant indexing plugin

I just installed the plugin and it caused my site to crash. Unable to login to admin panel. I have to use recovery mode to delete the plugin! Please make sure this kind of problem does not exist or you should not offer the plugin at all.

Here is the error:

Version 1.1.9 | By Rank Math | View details
This plugin failed to load properly and is paused during recovery mode.
