Why there is no inventory in my game?

I dont know why but there is no inventory in my game for some reason so whenever i get more than 10 tools in my backpack there is no way i can equip it.

Have you checked the … button in the top right corner?

Roblox New GUI Sort the inventory and player list button into one place to minimalize the amount of button in the main gui. Pretty confusing at first.

I am so dumb thanks! 30 characters
