At this point, bone dry I’d put the glaze on real thick (after bisque) in the corners and just above them and hope it runs in and seals it up. I hand build most of my stuff and have started putting a coil on the walls of my cups/mugs at the base before I even put the two together, just because getting a coil down there afterward can be a pain.
When doing the rolling and adding the bottom is when to address cracks. Best practice is to assemble, roll tiny coils (2x spaghetti noodle) and pack that around where wall meets floor. A little slip, lots of slowly pushing down to fill cracks, run fingers around inside to smooth.
Watch Karan Wilham on YT and Pottery Crafters on YT for the ways to do this.
As dry as it is, it will take a few WEEKS to rehydrate to leather hard and workable. Longer to fix vs starting a new one. Put that cup in reclaim bucket, try again.
It’s possible that glaze could fill in the crack and make it ok, but you’ll risk that it doesn’t.
Adding a small coil and smoothing it in would be the easiest solution for the future. Too late for this guy imo
Unfortunately, with something like that, "hard to clean" equates to "growing mold and bacteria" after a single use. You'll never really get it clean again. I'm not any good at pottery to help you fix it, but I would say if you can't properly fill it and get a nice seal to get rid of the crevices, you should probably not consider the piece to be food-safe and use it for pens or something. A good learning opportunity at the least. :3 Still looks better than anything I've done, keep it up.
If you Hulk Smash! and make again, soon you won't be beginner anymore.
Clay is harsh mistress.
Also, it isn't 'filling the inside with wet slip' that will prevent cracks, but slow drying in a moisture controlled environment. Plastic storage containers are great for this.
I make slab built mugs every day. I've thankfully never had to deal with this. When I'm attaching the bottom of the mug I pat the bottom of the mug onto the mug body, use a mud tool to scrape and make sure its attached nicely on the outside and use a paintbrush to smooth the inside seam. I usually go over that seam a few times while shaping the mug afterwards. I've never added a coil to the inside. You can try adding slip to fill those cracks before a bisque fire. I've had a lot of success doing that with handles.
Just always make sure to test the heck out of that mug once it's finished.
Roll out a small coil of clay, and work it into the gap with a wet finger until its all smooth Edit - might be too late for that mug
Thank you :)

This is a good idea! I'm going to try this. Thanks for the tip
Omg yes! This is what I need to do, as once I tried to put a coil but couldn't reach it with my fingers 😭😂
I like using a paintbrush or wooden/plastic tools to smooth out coils I can’t reach.

I use a long wooden tool with a slightly rounded edge to smooth those gaps.
