If anyone could tell me what this thing is that has broken up in my bottom bracket. It looks to have been a ring or something that sat in a groove. Also should it be alright to ride on before I get it in for a service? if anyone knows please let me know 🙏🙏

DUB bottom bracket? It’s a blue o-ring. The seal is what keeps the water out of the bearing. I’ve seen a few bottom brackets wear out super quickly when these have been damaged at installation.
If the bearings feel fine I’d keep using the bottom bracket until it wears out completely. Just be super careful when you install the new one not to damage the seal. It’s really delicate.
