Some backend buttons not working on plugin

Hello guys, I’ve been having an error when I click some buttons on plugins on the backend of the web, they just don’t work. I tried the same buttons on another wordpress sites I have and they work just fine. I tried with incognito mode just in case it was something from the cache but doesn’t seem to be the problem. I’ve recorded a little video when I’m clicking the buttons… Video.

It would seem that the buttons not working are the ones that have some kind of popup (the ones that would take you to another page, either on the same site or another, work fine). I’ve deactivated the adblockers and it still does not work.

Does anyone know what could be causing this?

Thanl you in advance..
