Barclays Mobile Banking app on rooted device

Hi, i'm running the Pixel Experience ROM on my Nexus 6P, and my Barclays mobile banking app was working great as i used Magisk to hide it, but now when i go to open the app, it crashes for some odd reason. It was working for a while, then all of a sudden it stopped working. Now, can't get into it. I've tried uninstalling/reinstalling but that doesn't seem to do the trick.

I don't have any other apps installed like busybox or anything else like that.

Anyone know what's wrong, as i really need this app to work.

Any help would be appreciated.
