Add chuck pieces, brown sugar, soy sauce, sesame oil, chile-garlic paste, salt, and black pepper.

Close and lock the lid; be sure vent is closed. Select high pressure according to manufacturer's instructions; set timer for 45 minutes. Allow 10 to 15 minutes for pressure to build.

Step 3
Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid. Remove beef and shred.
