You probably have an HG11 freehub and not the older MTB HG standard, unless the bike is quite a bit older.
To put an 11 speed MTB cassette on the HG11 freehub requires a 1.85mm spacer behind the cassette. Is that spacer there? If not, are you sure what freehub you have? You can measure the length of it and/or tell us what year and model your bike or wheel is and people will figure it out I’d guess.
Missing or worn out spacers, or from what i can see there’s a bigger gap between 10th and 11th cog, so check if the last cog key sits properly.
Need a spacer behind the cassette.
Had the same thing while flipping cassettes around on my bikes – it needs a spacer, when you tighten the lockring does it bind/clickclickclick or does it just get smoothly tighter until it won’t move anymore?
If it’s not clicking then it’s not actually applying pressure, it’s just at the end of it’s threads
just replace the cassette looks like a mess
I had the same problem and posted about it. I just took it into the repair shop, can’t remember exactly what the guy told me about why it was happening, but it wasn’t in fact tighted properly

Could be dirty wheen you put it together.
Take it apart, clean it, and put it together
Hi, i had same cassette, same problem. It was still under warranty so i sent it back to bike shop, they only replaced lockring/locknut(not sure about terminology) and it fixed the issue.
had the same issue but by the time i figured out i need an extra spacer the cassette was damaged. I never managed to get it to stay tight. It was a used bike purchase and I guess the previous owner just rode the bike with this type of play. I hope it works for you when you install the spacer. I retired mine ..
I recently had a similar problem with an aluminium freehub. The problem was chewed-up splines on the freehub which prevented the cogs to sit freely due to interference, which resulted in the cassette loosening up after some harder rides (cogs would slide and settle on the cassette just a tiny bit).
The solution was to disassemble, file down the slightly raised chewed-up bits on the splines, reassemble everything while ensuring that each cog slides freely on the freehub, and tighten the lockring.
Need the appropriate washer that goes on the cassette body, then install the cassette. When it’s tightened up, everything will be secure.
Normal
same thing happened to me when i put a new hub, a spacer solved the issue.
5100 cassette? Looks like it? Iirc there’s a known issue where the rivets loosen. If nothing else has been changed it’s look at that. Sounds like you haven’t recently removed it so can’t point the finger at assembly. If it is that then new cassette I’m afraid.
