Pro Tools First Not Loading & Crashes With Pop Up Message
 

I'm trying to load protools first on my mac pro with scarlett solo 2nd gen but once it starts loading it stops & pop up with this message:

Could not complete your request because Assertion in "/Volumes/Development/212373/ProTools/AAE/Source/AAX/CFicAAXWidget.cpp", line 822.
(Use the Copy button to copy this message to the clipboard.).

This happened twice already and I was able to to change the volume settings, playback engine, and buffer size and it worked properly.
This time when I tried the same way by holding N down when loading, it just crashes and the same message pops up. How can I fix this? What does the pop up message mean?
Here's my specs:
MacBook Pro
Mac OS Sierra 10.12
Scarlett Solo 2nd gen
Pro tools first
