Describe the bug:

Riru doesn't seem to be working, even though it installed fine.

Additional context: Downloaded the debug zip from releases. Installed with Magisk, rebooted. Created a blank allow_install_app file in /data/adb/modules/riru-core/ Installed the Riru app from the archive. Here's what the Riru app says:

SELinux is enforcing and there are no incorrect rules related to Riru.

Riru not installed or not enabled.

Am I missing something? Please help. Attached a logcat reader log (for when I launched the app). logcat_06-24-2021_13-23-15.txt
