Hustle slide-in conflicts with some other plugins

I have Hustle Pro activated on my site. After I create a slide-in when I try to edit it gives me an error

 "There has been a critical error on your website". 

I went to a plugin conflict test and found that a couple of plugins are actually making conflict with it. The plugin lists are below:
All the AMP related plugins on my site
Gravity Forms
Smush Pro
Defender Pro
Hummingbird Pro

After I deactivated all these plugins the slide-in edit screen shows for me. But if I reactivate any of these plugins then it throws me that error and I can not access the page.
