Mysterious blank app - Malware?

Hello, I'm new here so I'm sorry if this is the wrong place to post this in.
So a while ago I installed some apps through apk files away from the play store(I have forgot what apps it was) , and ******** as I am I didn't check if they were safe. A while later I find this weird app with no thumbnail and no name, it had admin privileges, witch I have disabled ofc. I will link some screenshots below. If you have any idea of what it is and how to get rid of if I would be very happy if you could respond. And I'm not very keen on doing a system reset, but if that's what is required I guess I'll do it.

Thanks!

Wow I know I tried that, but it must have been before I disabled admin privileges. I feel really stupid now, Thanks so much and sorry for wasting your time.
