Hello, @Khubaib Khan,
If you deactivate the plugin, it will not create any issue on your site, and AMP is related to mobile speed, so some times other third party plugins conflict with AMP and that generate unexpected issues like on your site.
So if your site is working fine now, then no need to use the AMP plugin, you can deactivate it simply and go ahead.
