Is this a problem with the rear hub?
This happens too while riding, I’m pedaling and once I stop while still going the sprockets keep going so it makes the chain get all messed up,
Sorry for my English I’m not a native speaker
For reference it’s a Shimano 105
What’s wrong with my bike?

Yeah usually it’s the freehub . Sometimes it’s too much grease a little cleaning could solve it.
Someone can correct me if I’m wrong but I believe your cassette isn’t spinning because your freehub isn’t disengaging. The splines might be damaged or might be gummed up is my guess.
How does it work going forward?
Clean cassette and chain well. Lubricate chain and see if that solves issue. If that doesn’t work check chain and cassette for wear.
Rule 1: Try the easy solution first. As others have pointed out, that would be cleaning and lubricating.
However, if the cassette has recently been serviced, it may require a small spacer that goes on last. A mechanic that is in a hurry may forget that, as not all models utilize it; it’s about the size of a dime. If that is the case, it can also display this symptom.
Again, start with the easy stuff that doesn’t require disassembly of anything.
Nice paint color and wheels, very aesthetic!
Just an FYI you have a freewheel and not a cassette. The ones that come with new bikes can be pretty cheap especially if it’s a pandemic era freewheel. You can’t service these unless you want to drive yourself mad. A new one cost about $15 bucks.
It’s almost certainly an issue with the freehub. Most designs are fairly serviceable but in my experience the Mavic / ratchet types are easiest.
You’ve got yourself a fixie. Your free hub could have seized up. If you look at your rear hub, find the model number and search it + “Free hub service”.
Your free hub might be new? New hubs do that sometime, clean the springs and put oil instead of grease. Worked like a charm on mine, it doesn’t get dirty/gritty as much when I stopped using grease.
