I cannot turn off screen overlay

[AC Question]

So I updated my phone ( Xperia s7) to 6.0.1 and I cannot turn screen overlay off, I tried multiple methods to name the one wherein I had to turn off all the apps that had the draw over option, turning my phone to safe mode, and deleting clean master
None of those worked out for me and I cannot access most of my social media which is rather frustrating soo I'll appreciate any approach to this kind of problem
Thank you in advance!!
