HUD disappears after mounting an addon

I play Minecraft on mobile and I like to mod my worlds (Wither Storm, etc) and I have no problems playing one of my modded worlds, today is different though, I decide to play one of my modded worlds and I notice my HUD is missing (it loads after a few seconds but today it didn’t) so I think it’ll load after a few seconds, no, after 10 or so minutes it still hasn’t loaded so I decide to experiment with it, I make a unmodded world and my HUD is there, I then add a mod to the world and my HUD is gone, I don’t know what it is or why it’s doing that but I want it fixed.
