Suspicious script in debug text log of WordPress App

Hi.
I have a wordpress site : https://bit.ly/hzLRFB
Latest version

I was using wordpress app in both iphone and android phones.
Suddenly i could not login in both of them.
So i took a debug log from ios wordpress app.I saw that in the end there was a suspicious code : .So i think this is the problem. I searched every file and i couldn’t find this script! I deleted some other codes in index-header-footer , but the problem is there and i can see the script in the debug file of wordpress app. Please Help
