Subler won't open any existing m4a, m4v, mp4 files

[Punit Gor]

So Subler was working fine few days back. Suddenly now I can't open existing m4v, m4a mp4, etc Either right clicking and opening it with Subler or going from Subler's file menu, choosing open... I get no error. But the file doesn't open - local or from external drive. What works is when i Press File > New. That the only thing that works.

I uninstalled Subler restarted mac and reinstalled Subler (1.1.8) Can you help me figure the issue ?

Check if there are errors reported in the Console app.

This is the error in console. launchservicesd[78]: SecTaskLoadEntitlements failed error=22 Actually very random files are opening and some are just not opening. Even ones that i had previously edited in Subler. At times a file won't open if the app is already open but then when I quit the app and open it with the file that previously wasn't opening, it opens with the app startup.

No idea. Maybe something is wrong with your Mac OS install.
