[ONE Original Android Development] NoSpamDan:
Have you confirmed that you are properly rooted? Tried another file manager?

It seem syou have a selinux untrusted app denial, then I see some chatter in your log that appears related to amaze:

06-23 00:03:05.270 W/SearchServiceClient(4643): Starting with NO_SESSION handoverId is deprecated. Just don't. You will break.

Have you used it on Nougat before, and is it a root browser? It seems like it wasn't granted root access initially if so...
