Hey @FZ_TIANO,
Fortunately, the contents of a pack are added to your inventory immediately when you click to open it, even if you don't see the animation fully play out before it's interrupted by something else such as starting a match.
It doesn't look like the most recent pack contained any heirloom shards sadly, but it did have crafting materials as well as a Wingman and Peacekeeper skin which should be available if you check through your loadout.
Those were automatically added to your total as soon as you clicked to open the pack, so there would not have been any separate indication of crafting materials being added after the game.
You should still have the red dot notification for the new skins, though I've seen some situations where that doesn't appear if the opening animation is interrupted. Even if that's the case, you should be able to check through the actual list of skins to find the newer additions.
Fortunately it doesn't seem anything went missing here, though if you'd like to check into that further you'll need to speak with support directly.
You can open a new case using the steps on the EA Help website to get in touch with our support team so they can assist further.
