Need Help Updating

I host a small private server in Java Purpur 1.21.8. It includes plenty of datapacks, though one of them specifically is preventing me from updating to 1.21.11 since the datapack doesn't work there. I believe it can be removed but doing so wouldn't be very easy. It adds a new dimension and also a new structure in the overworld (but the structure only includes vanilla blocks). Nobody is currently inside the dimension. If anyone could help me, I really would appreciate it (updating the datapack also works by the way but it will be a short-term solution I guess). If anyone is interested in joining the server by the way (paid host), let me know (even if you don't deal with this issue). Thanks for reading!
