E/audit_log( 8383): Could not stat audit logfile /data/misc/audit/audit.log: Permission denied

That's smell like a permission issue right? Also hard to say without seeing your code. But I would suggest you to try simplifying the code as much as you could trying to see who's trying to write to this file and fix it

Closing as not enough information to debug and no user response.

Error looks like a library linking issue though. Maybe arising from flask?
